From 75b1521dae1ff1fde17fda2e30e591f2e5d64b6a Mon Sep 17 00:00:00 2001 From: Tomas Vondra Date: Thu, 24 Mar 2022 18:20:21 +0100 Subject: Add decoding of sequences to built-in replication This commit adds support for decoding of sequences to the built-in replication (the infrastructure was added by commit 0da92dc530). The syntax and behavior mostly mimics handling of tables, i.e. a publication may be defined as FOR ALL SEQUENCES (replicating all sequences in a database), FOR ALL SEQUENCES IN SCHEMA (replicating all sequences in a particular schema) or individual sequences. To publish sequence modifications, the publication has to include 'sequence' action. The protocol is extended with a new message, describing sequence increments. A new system view pg_publication_sequences lists all the sequences added to a publication, both directly and indirectly. Various psql commands (\d and \dRp) are improved to also display publications including a given sequence, or sequences included in a publication.
