Two possibilities:
1) Parse the tags (I have the code working): it's not that hard, the only
trick bit being recognizing the tags in the first place. I have assumed
that any bare unquoted string that is not preceded by valid identifier name
chars, and which starts with a '$' may be a dollar quote. This seems valid
to me.
2) We could avoid special coding for TOC entry types (eg. pg_restore
knowing 'FUNCTION' TOC entries should not be parsed), by changing the TOC
data to include a flag/counter (set by pg_dump) indicating that the entry
contains > 1 statements. Then we don't hard code knowledge of TOC entry
types, and function definitions will not be parsed. Old dump files would be
treated as multi-statement, and still be parsed.
If my assumption in (1) is valid, then I have a very mild preference for
it, but am happy with either.
