standby_config:
- standby_list { $$ = create_syncrep_config("1", $1); }
- | FIRST NUM '(' standby_list ')' { $$ =
create_syncrep_config($1, $4); }
+ standby_list { $$ =
create_syncrep_config("1", $1, SYNC_REP_PRIORITY); }
+ | ANY NUM '(' standby_list ')' { $$ =
create_syncrep_config($2, $4, SYNC_REP_QUORUM); }
+ | FIRST NUM '(' standby_list ')' { $$ =
create_syncrep_config($2, $4, SYNC_REP_PRIORITY); }
Reading again the thread, it seems that my previous post [1] was a bit
misunderstood. My position is to not introduce any new behavior
changes in 9.6, so we could just make the FIRST NUM grammar equivalent
to NUM.
