But why do you want to do that, if all that you have to do is specify
"recovery_target = 'immediate'" to recover to the end of the backup?
Because automation scripts do not know if transactions are available
after some point in time or not. But automation scripts know that
backup was completed successfully at that point.
For example:
We want to provide time to recover the database.
1. Base backup restored, wal files are applied successfully if there
is a transaction.
Doesn't "pg_basebackup --wal-method=stream" already do that?
Since the commands below automagically starts physical streaming, there must be a variation where all the wal data is applied but
doesn't start replication.
pg_basebackup --dbname=service=basebackup -D $PGDATA --progress --checkpoint=fast -v \
--write-recovery-conf --wal-method=stream --create-slot --slot=pgstandby1 --compress=server-zstd
pg_ctl start -w
Maybe just remove the two "slot" options:
pg_basebackup --dbname=service=basebackup -D $PGDATA --progress --checkpoint=fast -v \
--write-recovery-conf --wal-method=stream --compress=server-zstd
