Hi
I've checked the database size by meta command \l+ and even I checked
from file system level du -sh 49181 folder. 49181 is the db oid.
Minimal information is not going to solve this issue.
Provide the exact output of commands from:
1) The Primary database.
2) The Standby database.
3) Per post from Laurenz Albe, any objects in 49181/ that differ in size
between the primary and standby.
Also:
1) Describe the exact type of replication you are using?
2) The replication settings you are using.
3) The exact Postgres versions on both sides.
4) The OS and version on both sides.
5) Have you checked the Postgres logs on the standby side to see if the
server is showing any relevant errors?
Pgwal directory is same 40gb at primary and standby servers.
All the directories are of same size, 49181 folder (oid) is only
having different size.
Thanks,
Vinay kumar

How are you measuring the size?
If you are measuring on the files system what is the size of the base/
and pg_wal/ sub-directories in the %PG_DATA directoty?
