Hello I found that in 0001 you propose to rename few options. Probably we could rename another option for clarify? I think FAST (it's about some bw limits?) and WAIT (wait for what? checkpoint?) option names are confusing. Could we replace FAST with "CHECKPOINT [fast|spread]" and WAIT to WAIT_WAL_ARCHIVED? I think such names would be more descriptive.
- if (PQserverVersion(conn) >= 100000) - /* pg_recvlogical doesn't use an exported snapshot, so suppress */ - appendPQExpBufferStr(query, " NOEXPORT_SNAPSHOT"); + /* pg_recvlogical doesn't use an exported snapshot, so suppress */ + if (use_new_option_syntax) + AppendStringCommandOption(query, use_new_option_syntax, + "SNAPSHOT", "nothing"); + else + AppendPlainCommandOption(query, use_new_option_syntax, + "NOEXPORT_SNAPSHOT"); In 0002, it looks like condition for 9.x releases was lost? Also my gcc version 8.3.0 is not happy with v5-0007-Support-base-backup-targets.patch and produces: basebackup.c: In function ‘parse_basebackup_options’: basebackup.c:970:7: error: ‘target_str’ may be used uninitialized in this function [-Werror=maybe-uninitialized] errmsg("target '%s' does not accept a target detail", ^~~~~~ regards, Sergei
