Table 3-18. pg_language Columns

NameTypeReferencesDescription
lannamename Name of the language (to be specified when creating a function)
lanisplbool  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 sometime.
lanpltrustedbool  This is a trusted language. See under CREATE LANGUAGE what this means. If this is an internal language (lanispl is false) then this field is meaningless.
lanplcallfoidoidpg_proc.oid For non-internal 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.
lanvalidatoroidpg_proc.oid This references a language validator function that is responsible for checking the syntax and validity of new functions when they are created. See under CREATE LANGUAGE for further information about validators.
