Question

How can I find what languages have been loaded into EnterpriseDB(PL/pgsql, SPL, Java)? EnterpriseDB is built on top of PostgreSQL if anyone knows of a way to find the loaded languages on PostgreSQL. It should work the same.

Answer 1

The installed languages are registered in pl_language, e.g.:

steve@steve@[local] =# select * from pg_language;
 lanname  | lanowner | lanispl | lanpltrusted | lanplcallfoid | lanvalidator | lanacl
----------+----------+---------+--------------+---------------+--------------+--------
 internal |       10 | f       | f            |             0 |         2246 |
 c        |       10 | f       | f            |             0 |         2247 |
 sql      |       10 | f       | t            |             0 |         2248 |
 plpgsql  |       10 | t       | t            |         73259 |        73260 |
