I think it's time to sum up what we want to do:
- We'd like to use switches to export objects according to a pattern.
- For each object type we will have an --object=PATTERN flag and a
--exclude-object=PATTERN
- Having a short flag for each of the long flags is not mandatory
- The object types that pg_dump can select so far are:
- table (already written)
- schema (already written)
- extension (half-written, --exclude-extension not written)
- routine (TBD ASAP). Routine flag operates on stored functions, stored
procedures, aggregate functions, and window functions.
- By default, pg_dump does not export system objects but we found out that
we could use --table='pg_catalog.*' to export them. This is a bug and will
be fixed. pg_dump won't have the ability to export any system object
anymore. Should the fix belong to that patch or do I need to create a
separate patch? (Seems to me it should be separated)
If everyone is ok with the points above, I'll write both patches.
Have a nice day,
Lætitia
