Hey sql@,

Hey general@,
To be assured and just for calmness.
Problem:
1. CREATE TABLE test_tab (id integer, dat varchar(64));
2. INSERT INTO test_tab VALUES($1, $2) via PQexecParams,
where paramTypes[0] == OID of bigint,
paramTypes[1] == OID of text.
Questions:
Whether this case falls to
http://www.postgresql.org/docs/9.0/static/typeconv-query.html ?
Is such cases safe or it is recommended (best) to specify a
OIDs which are exact matches ?
PS.
I know, that queries like SELECT $1 does not work without
specifying OID or without rewriting it to e.g. SELECT $1::text.
Thanks.
