Relocated Postgres

HI,

I relocated an postgres instance. The pg_data, pg_tranlog, pg_hba.conf, etc were copied to new directories. Then, I updated the postgresql.conf accordingly. Postgres started ok, and I can connect. However when I stopped it, the following msg appeared at the errorlog:

cp: overwrite `/dba/psg/gs07/pg_tranlog/pg_archlog/00000001000000000000004C'? < 2015-03-10 20:50:38 EDT >LOG: database system is shut down

Postgres proceeded to shutdown.

'ls' showed that the file still have the old timestamp, which is the timestamp when I copied it over:

ls -ltr /dba/psg/gs07/pg_tranlog/pg_archlog/00000001000000000000004B
-rw------- 1 gs07 dbagroup 16777216 Mar 10 12:07 /dba/psg/gs07/pg_tranlog/pg_archlog/0000000100

I did not have any transctions, though between the start-up and shutdown. I would have expected the timestamp of the logfile to have been changed.
Looks like it was waiting for a response to 'cp'.

I am concerned that if there were any transactions, I would have lost it.
Pls advice.

Thanks.

Maria
