; to 1000. That gave me
the value of estimated number of rows for subscr_param_pkey closer to the real
value (est.64, real 30) which affected the execution plan in the right way.

of the number of rows to

And my question:
1. am i right in my hypothesis?
2. is there a way to affect the cost evaluation in my case to help postgresql
choose the right execution plan?
3. is there a way to fix this query and not to break the execution of other
queries?
ps: running "analyze" on both tables doesn't affect the result
pps: all "cost" parameters are in their default values: cpu_index_tuple_cost,
cpu_operator_cost, cpu_tuple_cost, random_page_cost, seq_page_cost.
Thanks, Mikhail

6.1) or there is another quick way to check if
i should apply some additional actions to standard pg_upgrade+stats_collect?

s the same: no action performing by process.
The situation is reproducible: i can interrupt the process, run index renaming
again and i'll get the same situation, described above.
Is there any ideas what is happening inside the database?

Sorry for my previous message, it went to wrong thread. Creating this as a new
one.
I'm running supposedly an easy operation - renaming index and my session hangs
on it. pg_stat_activity shows that process is active and is waiting for lock:
=# select application_name, waiting, state, query
ore; 2. they restore with their
locks on database objects; 3. if you're restoring using PITR, you should
rollback all the prepared transactions after database start.
Thank you, Tom.

Hi,
I have a long executing query via foreign data wrapper and on the remote server
i can see that the query is fetching data from the cursor
=# select application_name, state, query from pg_stat_activity where pid =
15455;
application_name │ state │ query
(QueryExecutorImpl.java:257)
Could you please help me to figure out the reason of such a failure. (This
bug happens once per 10 successful cases.)
Thanks in advance!
Best regards, Mike Pryakhin.

Is there any reasonable way to do it in sql/pgplsql?
Thanks in advance.

I installed Postgresql from RedHat 5EL RPMS from the site. When I try to start
it as a service, it fails and pgstartup.log contains one record per startup
attempt stating: runuser: warning: cannot change directory to /dev/null: Not a
directory.
Thanks!

We are considering using Postgresql for rather large project and I have

May I use function with parameters with triggers?
When I try it I have error: "Can't find function ..".
Is it normal?
