Thanks!   I have obtained my query! Here is:

SELECT  (SELECT relname FROM pg_catalog.pg_class WHERE oid=conrelid) AS
fromTbl, (SELECT relname FROM pg_catalog.pg_class WHERE oid=confrelid) AS
toTbl, (SELECT attname FROM pg_catalog.pg_attribute WHERE attrelid=conrelid
AND conkey[1]=attnum) AS viaCol
FROM pg_catalog.pg_constraint AS rel WHERE contype='f';

TIA
