Postgresql 15 preview - sequence 支持逻辑复制

PostgreSQL 15版本之前的逻辑复制支持表上的 delete, insert, update, truncate, 现在sequence 也支持了。看逻辑复制的DDL邮件组也十分活跃，期待在15中也得到支持。

    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.
