Thread: pgsql: Remove some dead code for handling XLOG_DBASE_CREATE_OLD and

Log Message:
-----------
Remove some dead code for handling XLOG_DBASE_CREATE_OLD and
XLOG_DBASE_DROP_OLD WAL records -- these records are no longer created in
current sources. Adjust numbering of XLOG_DBASE_CREATE and XLOG_DBASE_DROP
and bump the catversion. Patch from Gavin Sherry, adjusted by Neil Conway.
