Hi,
Thanks for the response.
I tried with the your sources and found the same issue.
I explain the steps that I followed, just to avoid any gaps in
understanding.
1) I assumes that the patch was already applied in your sources. So did
went ahead doing "configure", "make" and "make install"
2) Built pg_standby and copied manually to postgres bin directory
3) Copied the test_sync_repl.sh in postgres directory
4) Run the script. Refer "startup.log". Also verified the walsender and
walreceiver processes are running. Refer "ps.log".
Tests done:
1) Execute "psql -l". Refer "list_database.log"
2) Login to standby with command "psql -d replication" and execute SQL
"select * from pg_roles;". This worked fine.
3) Login to primary with command "psql -d postgres" and execute SQL
"create table temp1 (int int);". On execution of this query the standby
instance came down. Refer "createTable.log" (printed on console)
One of the hacker suggested to remove the "echo "host all all 0.0.0.0/0
trust" >> ${SBYDATA}/pg_hba.conf" for standby database only. But here
too the result was same.
Environment that I use:
- RHEL 4.7
- Both Primary & standby in the same machine
Could you please help. If you need any more symptoms, I can re-work.
Thanks,
Niranjan
