You need to create the extension in the database that you want to use it in. From the output that you posted, it looks like you created the extension in the “postgres” database but you tried to use it in the “db” database.

Subject: [ADMIN] Postgres 9.5 pg_prewarm
Hi all,
I have just migrated my db to PG 9.5, an I would like to use pg_prewarm contrib function, but when I want to use it, I have an error message I don't understand :
It should do this :
1. postgres=# select pg_prewarm('foo');
2. pg_prewarm
3. ------------
4. 113278
5. (1 row)
but it do that :
psql (9.5.0)
postgres=# create extension pg_prewarm;
CREATE EXTENSION
db=# select pg_prewarm('accounts');
ERROR: function pg_prewarm(unknown) does not exist
LINE 1: select pg_prewarm('accounts');
^
HINT: No function matches the given name and argument types. You might need to add explicit type casts.
(table accounts exists)
Does anyone have an idea ?
Thanks,
thomas
