record_inspect defines functions which allow introspection of record and composite types from PL/pgSQL and PL/SQL. record_inspect defines the following database objects, all in the schema record_inspect. * fieldinfo [composite type] Used to by fieldinfos() to describe a record's fields. Contains the fields fieldname (name), fieldtype (regclass), fieldtypemod (varchar) * fieldinfo fieldinfos(record) Returns an array of <fieldinfo>s describing the record''s fields * anyelement fieldvalue(record, field name, defval anyelement, coerce boolean) Returns the value of the field <field>, or <defval> should the value be null. If <coerce> is true, the value is coerced to <defval>'s type if possible, otherwise an error is raised if the field''s type and <defval>'s type differ. * anyelement fieldvalues(record, defval anyelement, coerce boolean) Returns an array containing values of the record'' fields. NULL values are replaced by <defval>. If <coerce> is false, only the fields with the same type as <defval> are considered. Otherwise, the field'' values are coerced if possible, or an error is raised if not. Installation: ------------- Do make install or make PG_CONFIG=/path/to/your/pg_config install This will install record_inspect.so into <prefix>/lib (or <prefix>/lib/postgresql) and record_inspect.sql into <prefix>/share/contrib (or <prefix>/share/postgresql/contrib). Before you're able to use record_inspect from a specific database, you need to register the types and functions of record_inspect with that database. This is what record_inspect.sql is for. Simply do psql your_database < record_inspect.sql
