I have multi-tenant postgres DB. I can see details from pg_stat_statements table in the public schema with no issues, but as soon as I switch to a different schema - I get no visibility.
What could be done?
prod=> SET search_path=schema_name;
SET
prod=> SELECT substring(query, 1, 130) AS query,
calls,
round(total_exec_time::numeric, 2) AS total_time,
round(mean_exec_time::numeric, 2) AS mean_time,
round((100 * total_exec_time / sum(total_exec_time) OVER ())::numeric, 2) AS percentage
FROM pg_stat_statements
ORDER BY mean_exec_time DESC
LIMIT 10;
ERROR: relation "pg_stat_statements" does not exist
LINE 6: FROM pg_stat_statements
^
prod=> create extension pg_stat_statements;
ERROR: extension "pg_stat_statements" already exists

Is an INSERT INTO x... query ever issued from sqlalchemy?
The code to insert a few rows is:
session = Session(engine)
user1 = User(id=None, name='squidward', fullname='Squidward Tentacles')
user2 = User(...)
session.add(user1)
session.add(user2)
session.commit()
Then later on checking in postgres pg_stat_statements - there is not INSERT INTO users ... query.
It is certain that the correct instance is being checked.
Why is the query not showing up in pg_stat_statements?
Based on past experience and documentation related to search_path:
"The first matching table in the search path is taken to be the one wanted. If there is no match in the search path, an error is reported, even if matching table names exist in other schemas in the database."
But when I run this:
financialdw=> show search_path;
search_path
------------------------------------------------------
"$user, prismdms, prism_nonrestrict, prism_restrict"
(1 row)
financialdw=> select count(*) from addr;
ERROR: relation "addr" does not exist
LINE 1: select count(*) from addr;
^
financialdw=> select count(*) from prismdms.addr;
count
-------
24428
(1 row)
prismdms is in my search_path and I have the necessary permissions on all tables within it. Shouldn't I be able, as the document states, query the table without the schema name qualifying it?
Your search_path has a single schema in it, and that single schema has the long and unlikely name of $user, prismdms, prism_nonrestrict, prism_restrict.
The double quotes should just be around $user, not the entire thing.
I am getting an error while loading Raster data to a postgres table

Any idea on this?
I have below extensions present in the database where I am trying to create the table:
CREATE EXTENSION postgis
CREATE EXTENSION postgis_topology
CREATE EXTENSION fuzzystrmatch
Please help me on this If you have any idea.
My search path set for the database is ::
search_path
----------------------------------------------
"$user", public, rasters, postgis, pg_catalog
post_GIS version
SELECT postgis_version();
postgis_version
---------------------------------------
2.1 USE_GEOS=1 USE_PROJ=1 USE_STATS=1
Please let me knwo if you havve face this issue earlier.
I'm using the Looker Dashboarding software (see: looker.com). It creates temporary tables in your database's looker_scratch schema with long names, each containing a dollar symbol.
These are straightforward to query using the "SQL Runner" in Looker itself, which somehow is able to escape the dollar symbol, but I can't query them using a 3rd-party SQL client.
I'm trying to query this table:
SELECT *
FROM looker_scratch.LR$5UA5D3XQDBPAYU0Q9FLFE_test
but get the error:
the # of binded parameters < the # of parameter markers
How can I query the table?
I've tried:
...FROM looker_scratch."LR$5UA5D3XQDBPAYU0Q9FLFE_test" - says the relation does not exist
...FROM looker_scratch."LR\$5UA5D3XQDBPAYU0Q9FLFE_test" - says the relation does not exist
...FROM looker_scratch.$LR\$5UA5D3XQDBPAYU0Q9FLFE_test$ - says syntax error
...FROM looker_scratch.$$LR\$5UA5D3XQDBPAYU0Q9FLFE_test$$ - says syntax error
...FROM looker_scratch.E'LR\$5UA5D3XQDBPAYU0Q9FLFE_test' - says syntax error
try selecting exact identifier by pattern:
select oid::regclass from pg_class where relname ilike '%5ua5d%';
E.g:
so=# create table t."WeirdMix$" ();
CREATE TABLE
Time: 55.750 ms
so=# select oid::regclass from pg_class where relname ilike '%mix%';
oid
---------------
t."WeirdMix$"
(1 row)
Time: 90.814 ms
I've created a table in postgresql which is OK and I'm able to do select/insert using SQL manager tool or Navicat Lite tool.
But, when I'm trying to make simple select from LINUX(ubuntu) I have following message:
postgres=# select count(*) from stg_data_brest_surgery;
ERROR: relation "stg_data_brest_surgery" does not exist
STATEMENT: select count(*) from stg_data_brest_surgery;
ERROR: relation "stg_data_brest_surgery" does not exist.
I also used table name with double quotes - same result.
Any idea what's the issue?
Chances are the schema isn't in your search path, Try \dn to list namespaces and then you can either add the schema like:
SELECT * from "schema"."table";
Or you can set your search path:
SET search_path="schema";
SELECT * FROM "table";
RESET search_path;
