This reverts a sequence of commits, implementing features related to logical decoding and replication of sequences: - 0da92dc530c9251735fc70b20cd004d9630a1266 - 80901b32913ffa59bf157a4d88284b2b3a7511d9 - b779d7d8fdae088d70da5ed9fcd8205035676df3 - d5ed9da41d96988d905b49bebb273a9b2d6e2915 - a180c2b34de0989269fdb819bff241a249bf5380 - 75b1521dae1ff1fde17fda2e30e591f2e5d64b6a - 2d2232933b02d9396113662e44dca5f120d6830e - 002c9dd97a0c874fd1693a570383e2dd38cd40d5 - 05843b1aa49df2ecc9b97c693b755bd1b6f856a9 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
