I got no result back, but when using SQL:select * from pg_proc where proname = 'xxx', I got what I want, and the result OID is just the one in the first SQL.Then I reindex pg_proc, retry the first SQL, the result is correct.

Well, apparently you did the restore incorrectly, leading to an
inconsistent index on pg_proc. Since you proided no details about how
you did that, it's hard to say more.
