This is wrong because you are looking at only one indkey position, and
the attribute could be in any position of the primary key. I think
what you want is to drop pga2 from the query and instead use something
like
... and pga1.attnum in (i.indkey[0], i.indkey[1], i.indkey[2], ...)
(carrying it out to whatever you think is a reasonable upper bound on
the number of columns in a primary key --- the normal Postgres limit
is 32 keys but I can't believe anyone would use that many in practice).
