PostgreSQL cannot generate uuid but uuid-ossp extension is installed? - postgresql

postgresql11-server-11.8_2
When I try to add a new client in idempiere I get the following error message:
idempiere Version=7.1.0.202008290007
Initial Client Setup Process
Do you want to start the Process?
** org.postgresql.util.PSQLException: ERROR: function uuid_generate_v4() does not exist Hint: No function matches the given name and argument types. You might need to add explicit type casts. Where: PL/pgSQL function generate_uuid() line 3 at RETURN
This usually indicates that the uuid extension is missing from the database. But this is not the case.
[root#accounting-2 ~ (master)]# sudo -u postgres psql --dbname=idempiere
psql (11.8)
Type "help" for help.

plpgsql | 1.0 | pg_catalog | PL/pgSQL procedural language
uuid-ossp | 1.1 | public | generate universally unique identifiers (UUIDs)
What is causing this? How is it fixed?

The output of \dx in my postgres looks like this:
plpgsql | 1.0 | pg_catalog | PL/pgSQL procedural language
uuid-ossp | 1.1 | adempiere | generate universally unique identifiers (UUIDs)
In your case it shows uuid-ossp installed in the public schema, while in my case is installed in adempiere schema.
Please try the following command in your idempiere database:
CREATE EXTENSION "uuid-ossp"

Timescale: ERROR: tried calling catalog_get when extension isn't loaded

I'm using Timescale and today I faced on a problem:
I`m creating a simple table with any of bellow ways:
1-
> create table if not exists "NewTable" as (select * from "OldTable");
SELECT 6
2-
create table "NewTable" ("eventTime" timestamptz, name varchar);
after the table successfully created. I write \d and the result for both tables are same:
Column | Type | Collation | Nullable | Default
-----------+--------------------------+-----------+----------+---------
eventTime | timestamp with time zone | | |
name | character varying | | |
but the problem starts here...
> SELECT create_hypertable('"NewTable"', '"eventTime"' ,migrate_data => true);
ERROR: tried calling catalog_get when extension isn't loaded
so after I googled my issue I found nothing usefull insted of everyone told to create timescaledb extention that I had it before
> CREATE EXTENSION timescaledb CASCADE; //OR CREATE IF NOT EXISTS EXTENSION timescaledb CASCADE;
ERROR: extension "timescaledb" has already been loaded with another version
and
> \dx
Name | Version | Schema | Description
-------------+---------+------------+--------------------------------------------------------
plpgsql | 1.0 | pg_catalog | PL/pgSQL procedural language
timescaledb | 1.5.1 | public | Enables scalable inserts and complex queries for time-series data
so what should I do?
Question : why this happened? how should I create a hyper table now?
before these operations, I tried to take a dump from my database and before that, I have 20 main_hyper_tables.
why this happened?
I guess TimescaleDB was installed in the standard way through apt. Since new version of TimescaleDB (v.1.6) was released recently, apt automatically updated installation and copied the binary of 1.6 into the shared library of PostgreSQL installation. Thus new extension version was loaded, which is different from the extension used to create the database (v.1.5.1).
how should I create a hyper table now?
I see two options:
Load the extension version used to create the database, by explicitly specifying in the postgres config.
Update the extension to the latest version by
ALTER EXTENSION timescaledb UPDATE
See using ALTER EXTENSION section in Update TimescaleDB doc

If you are talking about this extension, I am not surprised.
The extension does not define a data type or domain called period.

pg_stat_statements enabled, but the table does not exist

I've postgresql-9.4 up and running, and I've enabled pg_stat_statements module lately by the help of official documentation.
But I'm getting following error upon usage:
postgres=# SELECT * FROM pg_stat_statements;
ERROR: relation "pg_stat_statements" does not exist
LINE 1: SELECT * FROM pg_stat_statements;
postgres=# SELECT pg_stat_statements_reset();
ERROR: function pg_stat_statements_reset() does not exist
LINE 1: SELECT pg_stat_statements_reset();
I'm logged in to psql with the postgres user.
I've also checked the available extension lists:
postgres=# SELECT * FROM pg_available_extensions WHERE name = 'pg_stat_statements'
;
name | default_version | installed_version | comment
--------------------+-----------------+-------------------+-----------------------------------------------------------
pg_stat_statements | 1.2 | | track execution statistics of all SQL statements executed
(1 row)
And here's the results of the extension versions query:
postgres=# SELECT * FROM pg_available_extension_versions WHERE name = 'pg_stat_statements';
name | version | installed | superuser | relocatable | schema | requires | comment
--------------------+---------+-----------+-----------+-------------+--------+----------+-----------------------------------------------------------
pg_stat_statements | 1.2 | f | t | t | | | track execution statistics of all SQL statements executed
(1 row)
Any help will be appreciated.
Extension isn't installed:
SELECT *
FROM pg_available_extensions
WHERE
name = 'pg_stat_statements' and
installed_version is not null;
If the table is empty, create the extension:
CREATE EXTENSION pg_stat_statements;
I've faced with this issue at configuring Percona Monitoring and Management (PMM) because by some strange reason PMM connecting to database with name postgres, so pg_stat_statements extension have to be created in this database:
yourdb# \c postgres
postgres# CREATE EXTENSION pg_stat_statements SCHEMA public;
Follow below steps:
Create the extension
CREATE EXTENSION pg_stat_statements;
Change in config
alter system set shared_preload_libraries='pg_stat_statements';
Restart
$ systemctl restart postgresql
Verify changes applied or not.
select * from pg_file_Settings where name='shared_preload_libraries';
The applied attribute must be 'true'.
I Had the same issue when deploying the environment using liquibase for the first time.
I understand that my reply maybe is not related with your problem but was the first google result so I think that other guys like me can arrive here with my the same Liquibase Issue.
These are PosGreSQL metadata tables that are retrieved by liquibase when you generate your first xml file.
In my case it only was useless autogenerated code, so I solved it deleteing these lines:

Extension exists but uuid_generate_v4 fails

At amazon ec2 RDS Postgresql:
=> SHOW rds.extensions;
rds.extensions
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(1 row)
As you can see, uuid-ossp extension does exist. However, when I'm calling the function for generation uuid_v4, it fails:
CREATE TABLE my_table (
id uuid DEFAULT uuid_generate_v4() NOT NULL,
name character varying(32) NOT NULL,
);
What's wrong with this?
The extension is available but not installed in this database.
CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
If the extension is already there but you don't see the uuid_generate_v4() function when you do a describe functions \df command then all you need to do is drop the extension and re-add it so that the functions are also added. Here is the issue replication:
db=# \df

What probably happened is that the extension was originally added to the cluster at some point in the past and then you probably created a new database within that cluster afterward. If that was the case then the new database will only be "aware" of the extension but it will not have the uuid functions added which happens when you add the extension. Therefore you must re-add it.
Looks like the extension is not installed in the particular database you require it.
You should connect to this particular database with
\CONNECT my_database
Then install the extension in this database
CREATE EXTENSION "uuid-ossp";
Step #1: re-install uuid-ossp extention into the exact schema:
If this is a fresh installation you can skip SET and DROP. Credits to #atomCode (details)
SET search_path TO public;
DROP EXTENSION IF EXISTS "uuid-ossp";
CREATE EXTENSION "uuid-ossp" SCHEMA public;
After this, you should see uuid_generate_v4() function IN THE RIGHT SCHEMA (when execute \df query in psql command-line prompt).
Step #2: use fully-qualified names (with schemaname. qualifier):
For example:
CREATE TABLE public.my_table (
id uuid DEFAULT public.uuid_generate_v4() NOT NULL,
If you've changed the search_path, specify the public schema in the function call:
public.uuid_generate_v4()
This worked for me.
create extension IF NOT EXISTS "uuid-ossp" schema pg_catalog version "1.1";
make sure the extension should by on pg_catalog and not in your schema...
Just add this code to the Beginning of your script
DROP EXTENSION IF EXISTS "uuid-ossp";
CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
Maybe It was the same I was facing. The uuid_generate_v4 was from the public schema and I was trying to run it in a specific schema, so to fix it I did:
SET search_path TO specific_schema;
INSERTO INTO my_table VALUES public.uuid_generate_v4();
You can check the schema where your function is running:
\df uuid_generate_v4
Or
SELECT n.nspname, p.probin, p.proname
FROM
pg_proc p
LEFT JOIN pg_namespace n ON p.pronamespace = n.oid
WHERE p.proname like 'uuid_generate_v4';
You can check info related to the extension of the uuid-ossp like this:
SELECT * FROM pg_extension WHERE extname LIKE 'uuid-ossp';
You can add this extension case you don't have it already:
CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
if you do it from unix command (apart from PGAdmin) dont forget to pass the DB as a parameter. otherwise this extension will not be enabled when executing requests on this DB
psql -d -c "create EXTENSION pgcrypto;"
in my case were 3 steps. Create the database, connect to the database and create the extension. The important step is the second one, "connect to the database", and you can notice the line without ";" cause is a command and not a SQL sentence.
CREATE DATABASE database_name_here;
\connect database_name_here
CREATE EXTENSION IF NOT EXISTS "uuid-ossp";

PostgreSQL procedural language "C" not found

I am trying to use the PL/R procedural language in a PostgreSQL 9.2 database. I have installed the plr language and I am trying to add it to a database. When I run the command CREATE EXTENSION plr; I get the following error:
ERROR: language "C" does not exist
STATEMENT: CREATE EXTENSION plr;
ERROR: language "C" does not exist
When I list the available languages in the database with select * from pg_language; I get
lanname | lanowner | lanispl | lanpltrusted | lanplcallfoid | laninline | lanvalidator | lanacl
----------+----------+---------+--------------+---------------+-----------+--------------+--------
internal | 10 | f | f | 0 | 0 | 2246 |
c | 10 | f | f | 0 | 0 | 2247 |
sql | 10 | f | t | 0 | 0 | 2248 |
plpgsql | 10 | t | t | 12514 | 12515 | 12516 |
(4 rows)
So there is a language c but it is not in capital letters (not sure if that makes a difference).
I am wondering why the plr extension does not find the C procedural language?
You are probably running into this change in PostgreSQL 9.2 (quoting the release notes here):
No longer forcibly lowercase procedural language names in CREATE
FUNCTION (Robert Haas)
While unquoted language identifiers are still lowercased, strings and
quoted identifiers are no longer forcibly down-cased. Thus for example
CREATE FUNCTION ... LANGUAGE 'C' will no longer work; it must be
spelled 'c', or better omit the quotes.
It's also reflected in the manual for CREATE FUNCTION
lang_name
The name of the language that the function is implemented in. Can be SQL, C, internal, or the name of a user-defined procedural
language. For backward compatibility, the name can be enclosed by
single quotes.
Quoting the language name has been discouraged since at least version 7.3 (maybe longer), but old habits die hard, obviously. Removing the quotes around 'C' fixes the problem, arriving at: LANGUAGE c or LANGUAGE C.
PL/R wasn't ready for PostgreSQL 9.2 in that respect, judging from the project page.
Feedback from Joe Conway
Joe Conway left an answer that got deleted because it should be a comment. I paste it here for the general public who can't see deleted answers:
I got the message, just haven't had the time to do a new PL/R release.
Look for it by December, but in the meantime the manual workaround
noted above is pretty simple.
I had a similar issue with pg_collkey. I believe your situation may have the same solution. Here's what I did: There's a .sql file in your postgres extension directory that tells postgres how to install the extension. In my case, it's called pg_collkey--0.5.0.sql. You'll need to modify that sql file. On my system (using Mac OS X and Homebrew) the file is located at /usr/local/share/postgresql/extension/pg_collkey--0.5.0.sql). It probably contains a capital "C" in the LANGUAGE clause, like so:
CREATE OR REPLACE FUNCTION collkey (text, text, bool, int4, bool) RETURNS bytea
LANGUAGE 'C' IMMUTABLE STRICT AS
'$libdir/collkey_icu.so',
'pgsqlext_collkey';
Change it to a lower-case 'c' and re-run the "CREATE EXTENSION pg_collkey;" command in psql:
psql -c 'CREATE EXTENSION pg_collkey;' my_database_name
Of course, you'll need to use "plr" instead of pg_collkey for the extension name.
