Re: Issue with installing postgres extension

thank you for tom for your response. i dont remember installing postgres 14
version on the server and it seems like I have postgres 15 running.

Please see below.

[postgres(at)postgres ~]$ psql
psql (15.7, server 15.0)
Type "help" for help.

postgres=#

postgres=# CREATE EXTENSION pg_stat_statements;
ERROR: could not load library
"/home/postgres/bin/pgsql/15/lib/pg_stat_statements.so":
/home/postgres/bin/pgsql/15/lib/pg_stat_statements.so: undefined symbol:
InitMaterializedSRF
postgres=#
postgres=# SELECT version();
version
