Are you sure? I have tested query with 3 table with multiple FK and
it works (see below) [as you can see
"C" table have two FK to A and B]
test=> SELECT
test-> (SELECT relname FROM pg_catalog.pg_class WHERE oid=conrelid)
AS fromTbl,
test-> (SELECT relname FROM pg_catalog.pg_class WHERE oid=confrelid)
AS toTbl,
test-> (SELECT attname FROM pg_catalog.pg_attribute WHERE
attrelid=conrelid AND conkey[1]=attnum) AS viaCol
test-> FROM pg_catalog.pg_constraint AS rel WHERE contype='f' ORDER BY
fromTbl;fromtbl | totbl | viacol
---------+-------+--------b | a | idac | a | idac | b | idb
