Thanks you. The FATAL message is not clear. Yes, It is helpful

Well if your interested in looking for yourself look here:
src/backend/utils/init/postinit.c
https://git.postgresql.org/gitweb/?p=postgresql.git;a=blob;f=src/backend/utils/init/postinit.c;h=0a4295b418132758ebd539f00175c32ac0db92d5;hb=6a18e4bc2d13d077c52cf90a4c6ec68343808ba7
Lines 781-879:
...
if (!superuser() && !has_rolreplication(GetUserId()))
ereport(FATAL,
(errcode(ERRCODE_INSUFFICIENT_PRIVILEGE),
errmsg("must be superuser or replication role to start
walsender")));
...
/*
* If this is a plain walsender only supporting physical replication, we
* don't want to connect to any particular database. Just finish the
* backend startup by processing any options from the startup packet, and
* we're done.
*/
....
/*
* If this is a background worker not bound to any particular
* database, we're done now. Everything that follows only makes sense
* if we are bound to a specific database. We do need to close the
* transaction we started before returning.
*/
To me it looks like settings are handled by process_settings at line
1101 and that is only called if an actual database is being connected to.
[postgres@pgserver ~]$ /opt/PostgreSQL/9.5/bin/pg_basebackup --format=t
--pgdata=online_backups1 -p 5432 -U *backup_admin* -x -z --verbose
*pg_basebackup: could not connect to server: FATAL: must be superuser
or replication role to start walsender*

Thanks for the reply,
Actually I am not setting Role for database specific,I did set
Role to
user.
Since users and roles are global for all databases in PostgreSQL,I
believe it should work for replication pesudo database.
Except for the part where the 'replication' database does not
actually exist, so I am not seeing how a connection could be
established to it. Now whether a replication connection is supposed
to honor SET ROLE is something someone with more knowledge of the
connection code will have to answer. The evidence says it does not.
Thanks,
Chiru
