Tom Lane	47888fe842	First phase of OUT-parameters project. We can now define and use SQL functions with OUT parameters. The various PLs still need work, as does pg_dump. Rudimentary docs and regression tests included.	21 years ago

This version has the seven fields I proposed, including "source". Here's an example that shows why I think it's valuable: regression=# \x Expanded display is on. regression=# select * from pg_settings where name = 'enable_seqscan'; -[ RECORD 1 ]----------- name \| enable_seqscan setting \| on context \| user vartype \| bool source \| default min_val \| max_val \| regression=# update pg_settings set setting = 'off' where name = 'enable_seqscan'; -[ RECORD 1 ]--- set_config \| off regression=# select * from pg_settings where name = 'enable_seqscan'; -[ RECORD 1 ]----------- name \| enable_seqscan setting \| off context \| user vartype \| bool source \| session min_val \| max_val \| regression=# alter user postgres set enable_seqscan to 'off'; ALTER USER (log out and then back in again) regression=# \x Expanded display is on. regression=# select * from pg_settings where name = 'enable_seqscan'; -[ RECORD 1 ]----------- name \| enable_seqscan setting \| off context \| user vartype \| bool source \| user min_val \| max_val \| In the first case, enable_seqscan is set to its default value. After setting it to off, it is obvious that the value has been changed for the session only. In the third case, you can see that the value has been set specifically for the user.

Tom Lane	549928d99b	Fix for breakage of C-coded SRFs, from Joe Conway.	24 years ago
Tom Lane	64505ed58b	Code review for standalone composite types, query-specified composite types, SRFs. Not happy with memory management yet, but I'll commit these other changes.	24 years ago
Tom Lane	30ec31604d	Add code to extract dependencies from an expression tree, and use it to build dependencies for rules, constraint expressions, and default expressions. Repair some problems in the original design of recursiveDeletion() exposed by more complex dependency sets. Fix regression tests that were deleting things in illegal sequences.	24 years ago
Bruce Momjian	95712b15b1	Add missing regression files for SRF.	24 years ago
