The comment in expand_dbname_patterns is ungrammatical and mentions "OID" rather than "name", so I suggest /* * The loop below might sometimes result in duplicate entries in the * output name list, but we don't care. */
Will fix.
I'm not sure this is grammatical either: exclude databases whose name matches PATTERN I would have written it like this: exclude databases whose names match PATTERN but I'm not sure (each database has only one name, of course, but aren't you talking about multiple databases there?)
I think the original is grammatical.
Other than that, the patch seems fine to me -- I tested and it works as intended. Personally I would say "See also expand_table_name_patterns" instead of "This is similar to code in pg_dump.c for handling matching table names.", as well as mention this function in expand_table_name_patterns' comment. (No need to mention expand_schema_name_patterns, since these are adjacent.) But this is mostly stylistic and left to your own judgement. In the long run, I think we should add an option to processSQLNamePattern to use OR instead of AND, which would fix both this problem as well as pg_dump's. I don't think that's important enough to stall this patch.
Thanks for the review. cheers andrew -- Andrew Dunstan https://www.2ndQuadrant.com PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
