version: PG8.2.2 MY Question: Why must "take the same number of parameters" ?
" We can check that all the referenced instances of the same support routine number take the same number of parameters" ? 1 there is no results by running regress test as follow: plsql/src/test/regress/sql/opr_sanity.sql ...... -- Unfortunately, we can't check the amproc link very well because the -- signature of the function may be different for different support routines -- or different base data types. -- We can check that all the referenced instances of the same support -- routine number take the same number of parameters, but that's about it -- for a general check... SELECT p1.amopclaid, p1.amprocnum, p2.oid, p2.proname, p3.opcname, p4.amopclaid, p4.amprocnum, p5.oid, p5.proname, p6.opcname FROM sys_amproc AS p1, sys_proc AS p2, sys_opclass AS p3, sys_amproc AS p4, sys_proc AS p5, sys_opclass AS p6 WHERE p1.amopclaid = p3.oid AND p4.amopclaid = p6.oid AND p3.opcamid = p6.opcamid AND p1.amprocnum = p4.amprocnum AND p1.amproc = p2.oid AND p4.amproc = p5.oid AND (p2.proretset OR p5.proretset OR p2.pronargs != p5.pronargs); But, contrib\tsearch2\tsearch.sql.in: ...

So, who can tell me whether the rule is right?
