Tom Lane 1111b2668d Undo decision to allow pg_proc.prosrc to be NULL. ... Commit e717a9a18 changed the longstanding rule that prosrc is NOT NULL because when a SQL-language function is written in SQL-standard style, we don't currently have anything useful to put there. This seems a poor decision though, as it could easily have negative impacts on external PLs (opening them to crashes they didn't use to have, for instance). SQL-function-related code can just as easily test "is prosqlbody not null" as "is prosrc null", so there's no real gain there either. Hence, revert the NOT NULL marking removal and adjust related logic. For now, we just put an empty string into prosrc for SQL-standard functions. Maybe we'll have a better idea later, although the history of things like pg_attrdef.adsrc suggests that it's not easy to maintain a string equivalent of a node tree. This also adds an assertion that queryDesc->sourceText != NULL to standard_ExecutorStart. We'd been silently relying on that for awhile, so let's make it less silent. Also fix some overlooked documentation and test cases. Discussion: https://postgr.es/m/2197698.1617984583@sss.pgh.pa.us		2021-04-15 17:17:20 -04:00
