Re: doc for pg_dump

Hi Peter -

sorry if this is the wrong place to ask - but I was looking for
some documentation of the pg_dump/pg_dumpall output format
AND/OR some pointers on how to recognize and correctly handle index
relations when grabbing all tables in a database.

Anyway - the error I get when using pg_dump (or pg_dumpall) is...

SET TRANSACTION command failed. Explanation from backend: \
'ERROR: parser: parse error at or near "transaction"'.

... which, from what I have found searching the postgresql site,
seems to indicate a mismatch in the version of pg_dump used -
OR funky values in one or more tables.

Either is certainly possible in my case, and I HAVE found some
funky values (even a col type of "_text") in the exercise of
writing a home-grown pg_dump.

I think I have been able to correct such bad cases in the output
I'm producing but I do not know the actual format of the pg_dump
(or pg_dumpall) output and I cannot find any documentation for that
format?

Perhaps none exists? But I thought this was a good place to
ask??

What I do now is just output a bunch of \connect/CREATE
record pairs and then a bunch of "COPY ... from stdin"
sections.

I'm pretty much for sure that I need to include some handling of the
index relations that exist in the current databases (really really
don't want to think about having to redo all of those by hand 8-], but,
at the moment, I'm recognizing them based on exceptions and simply
skipping them because I'm not sure how to snarf them.

Any pointers to docs or how-to's would be greatly appreciated.
