Given a statement, eg:
select foo from bar where col = $1
I'd really like to get the types deduced by the PostgreSQL parser for
the input variables ($1, etc.) and the result column(s). eg. it might
be $1 :: int4 and foo :: text, or whatever.
It seems from reading about PQprepare that getting the input types
isn't yet possible, but might be in future:
I have no idea where to start getting the result types.
Is this possible in some way? Is the data perhaps hidden in one of
the pg_* system tables?
Note that I don't want to actually execute the statement, just parse
