| lanname | name | | Name of the language |
| lanispl | bool | | This is false for internal languages (such as
SQL) and true for user-defined languages.
Currently, pg_dump still uses this
to determine which languages need to be dumped, but this may be
replaced by a different mechanism in the future
|
| lanpltrusted | bool | | True if this is a trusted language, which means that it is believed
not to grant access to anything outside the normal SQL execution
environment. Only superusers may create functions in untrusted
languages
|
| lanplcallfoid | oid | pg_proc.oid | For noninternal languages this references the language
handler, which is a special function that is responsible for
executing all functions that are written in the particular
language
|
| lanvalidator | oid | pg_proc.oid | This references a language validator function that is responsible
for checking the syntax and validity of new functions when they
are created. Zero if no validator is provided
|
| lanacl | aclitem[] | | Access privileges; see
GRANT and
REVOKE
