hi, Andy,
We are using streaming hot standby, no wal shipping.
I checked and base and pg_xlog. both are fine.
The extra space is used by /pg_multixact/members(about 5G) and
/pg_multixact/offsets(about 1.5G)
The doc said that pg_multixact contains multitransaction data used for
shared row locks. Is there some process that can clean these two folder when
the lock is not needed?
Thanks.
best,
Ying
