The need for dumping from such ancient servers has decreased to about nil in the field, so let's remove all the code that catered to it. Aside from removing a lot of boilerplate variant queries, this allows us to not have to cope with servers that don't have (a) schemas or (b) pg_depend. That means we can get rid of assorted squishy code around that. There may be some nonobvious additional simplifications possible, but this patch already removes about 1500 lines of code. I did not remove the ability for pg_restore to read custom-format archives generated by these old versions (and light testing says that that does still work). If you have an old server, you probably also have a pg_dump that will work with it; but you have an old custom-format backup file, that might be all you have. It'd be possible at this point to remove fmtQualifiedId()'s version argument, but I refrained since that would affect code outside pg_dump. Discussion: <2661.1475849167@sss.pgh.pa.us> |
