This allows us to specify the target relation with several expressions, 'relname', 'schemaname.relname' and OID in all pgstattuple functions. pgstatindex() and pg_relpages() could not accept OID as the argument so far. Per discussion on -hackers, we decided to keep two types of interfaces, with regclass-type and TEXT-type argument, for each pgstattuple function because of the backward-compatibility issue. The functions which have TEXT-type argument will be deprecated in the future release. Patch by Satoshi Nagayasu, reviewed by Rushabh Lathia and Fujii Masao.
