I'm trying to set up a database and have to create a function:
create or replace function uuid() returns uuid as 'moss_uuidgen', 'moss_uuidgen' language 'C' strict;
Every time I execute that postgre tells me that in the .so file there is an undefined symbol called palloc
I know this version of Postgresql is outdated but it seems to be the only version working with my project. Does anyone know why postgre doesn't seem to know palloc?
moss=# create or replace function uuid() returns uuid as 'moss_uuidgen',
moss-# 'moss_uuidgen' language 'C' strict;
FEHLER: konnte Bibliothek »/usr/lib/postgresql/8.4/lib/moss_uuidgen.so« nicht laden: /usr/lib/postgresql/8.4/lib/moss_uuidgen.so: undefined symbol: palloc
moss=# \q
moss#McWiki:/usr/local$
the source file is avialble here: https://foundry.openuru.org/hg/MOSS/file/3e78d60a5282/postgresql
I build the files using make and make install.
OS: Ubuntu Server 20.04 LTS with Postgre 8.4
Thanks for the help, I realised that I build the files for psql 9.4 and tried to use it with psql 8.4, what was really dumb. Now afte rebuilding with 8.4 it works fine (at least to create the function, db is still not working with my gameserver)

I'm trying to convert geometries to images, and the functions to do so don't seem to exist.
The following example is from the ST_AsRaster Docs WHich specify the requirements are Availability: 2.0.0 - requires GDAL >= 1.6.0.
SELECT ST_AsPNG(ST_AsRaster(ST_Buffer(ST_Point(1,5),10),150, 150));
This results in:
ERROR: function st_asraster(geometry, integer, integer) does not exist
LINE 1: SELECT ST_AsPNG(ST_AsRaster(ST_Buffer(ST_Point(1,5),10),150,...
I found some info that points towards needing GDAL drivers, however, when I try:
SELECT short_name, long_name FROM ST_GdalDrivers();
I get:
ERROR: function st_gdaldrivers() does not exist
LINE 1: SELECT short_name, long_name FROM ST_GdalDrivers();
I have no idea where to even go to try solving this, why don't the functions exist, was there some config I needed to add, some doc I didn't read?
Even the https://postgis.net/docs/RT_reference.html seems to suggest that it should "just work"?
This is installed from the package manager on Ubuntu 20.0.4.

You must have forgotten to install the postgis_raster extension:
CREATE EXTENSION postgis_raster;
This extension is new in PostGIS 3.0; before that, its objects were part of the postgis extension.
The documentation mentions that:
Once postgis is installed, it needs to be enabled in each individual database you want to use it in.
psql -d yourdatabase -c "CREATE EXTENSION postgis;"
-- if you built with raster support and want to install it --
psql -d yourdatabase -c "CREATE EXTENSION postgis_raster;"
I have PostgreSQL 9.6 installation on my Debian Stretch (9). When I want to use crypt() or gen_salt() functions, it says:
ERROR: function gen_salt(unknown, integer) does not exist
LINE 1: select gen_salt('bf', 8)
^
HINT: No function matches the given name and argument types. You might need to add explicit type casts.
How can I get these functions working?
Installed postgresql packages
You have to enable it using SQL:
CREATE EXTENSION IF NOT EXISTS pgcrypto;
You have to do it on each database that uses pgcrypto functions.
I'm using PGAFIS library for fingerprint matching. For this i have installed postgresql and having some user defined c functions.
PGAFIS contain makefile, .control file, sql and unpacked sql file everything
I have compiled and pgafis.so file for the same and everyfile is on right location.
In my PGAdmin-III when i run CREATE EXTENSION pgafis it gives me following error:
ERROR: could not load library "/usr/lib/postgresql/9.4/lib/pgafis.so": /usr/lib/postgresql/9.4/lib/pgafis.so: undefined symbol: lfsparms_V2
SQL state: XX000
Please help. Thanks in advance
(This is a follow-up from Postgresql user defined c function issues)
I expect you forgot to link to the required library.
Try adding
PG_LIBS = -lmindtct
or whatever. If it's not on the default linker path you'll need to need to add -L/path/to/the/containing/directory to PG_CPPFLAGS too.
I'm using extensions and had no problems so far.
Now I create a new one, and when I call
create extension util;
I get in PG 9.2:
$ create extension util;
FEHLER: Syntaxfehler bei »«
ZEILE 1: create extension util;
and in PG 9.1 :
CREATE EXTENSION util;
ERROR: syntax error at or near "create"
LINE 1: CREATE EXTENSION util;
I have an util--1.0.sql , and even when this file is empty I get the error.
my util.control looks like this:
comment ='Hilfsfunktionen für Updateskripte'
default_version = '1.0'
schema=system
Any hints ?

I'm pretty sure that the server you're connecting to is neither 9.1 nor 9.2. Connect to it and run SELECT version(); to confirm.
I am running PostgreSQL 8.4.4 with Ubuntu 10.04.
I am trying to generate uuid but can't find a way to do it.
I do have the uuid-ossp.sql in /usr/share/postgresql/8.4/contrib/uuid-ossp.sql
When I try this is what I get :
postgres=# SELECT uuid_generate_v1();
ERROR: function uuid_generate_v1() does not exist
LINE 1: SELECT uuid_generate_v1();
^
HINT: No function matches the given name and argument types. You might need to add explicit type casts.
Any idea ?
The stuff in contrib aren't run automatically. You have to run it yourself to install the functions. I don't know about the 8.4 version, but in the 8.3 version it appears to only install it per-database, so open up the database you're using in psql and issue the command \i /usr/share/postgresql/8.4/contrib/uuid-ossp.sql
I saw this in my PostgreSQL travels. It requires the pgcrypto contrib module.
