oid

Row identifier (hidden attribute; must be explicitly selected)

lanname

name

Name of the language

lanowner

oid

pg_authid.oid

Owner 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 might 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 can 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

laninline

oid

pg_proc.oid

This references a function that is responsible for executing “[.quote]#inline”# anonymous code blocks (DO blocks). Zero if inline blocks are not supported.

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
