Rename pg_sequence_read_tuple() to pg_get_sequence_data()
This commit removes log_cnt from the tuple returned by the SQL function.
This field is an internal counter that tracks when a WAL record should
be generated for a sequence, and it is reset each time the sequence is
restored or recovered. It is not necessary to rebuild the sequence DDL
commands for pg_dump and pg_upgrade where this function is used. The
field can still be queried with a scan of the "table" created
under-the-hood for a sequence.
Issue noticed while hacking on a feature that can rely on this new
function rather than pg_sequence_last_value(), aimed at making sequence
computation more easily pluggable.
Bump catalog version.
