This reverts a sequence of commits, implementing features related to logical decoding and replication of sequences: -0da92dc530
-80901b3291
-b779d7d8fd
-d5ed9da41d
-a180c2b34d
-75b1521dae
-2d2232933b
-002c9dd97a
-05843b1aa4
The implementation has issues, mostly due to combining transactional and non-transactional behavior of sequences. It's not clear how this could be fixed, but it'll require reworking significant part of the patch. Discussion: https://postgr.es/m/95345a19-d508-63d1-860a-f5c2f41e8d40@enterprisedb.com
