in pghackers list. Support for oldstyle internal functions is gone (no longer needed, since conversion is complete) and pg_language entry 'internal' now implies newstyle call convention. pg_language entry 'newC' is gone; both old and newstyle dynamically loaded C functions are now called language 'C'. A newstyle function must be identified by an associated info routine. See src/backend/utils/fmgr/README. |
