Dovecot and reconnection to database

I've got a setup with Dovecot using a PostgreSQL backend together with vmm. I usually get messages like this into log:

dovecot: dict: pgsql(10.0.0.2): Connected to database mail

Based on investigation I think it's because Dovecot is losing/closing connection to the PostgreSQL server. Is there any way to tell Dovecot to keep connection alive?

What about this makes you think that the connections need to stay alive, instead of being cycled occasionally? – NickW Apr 23 '14 at 14:38
I'm still connected with a bunch of IMAP clients. – frlan Apr 23 '14 at 14:40
Do you see extra load due to dovecot cycling the connections? – NickW Apr 23 '14 at 14:47
Well... a little. It's about 100 reconnections per hour roughly. well... I know something I can deal with it, but as it's appearing to increase with numbers of clients ... – frlan Apr 23 '14 at 14:49
You know what dict is doing in this case, right? – NickW Apr 23 '14 at 15:09
I assume it's trying to get the path where to put the mail into. – frlan Apr 23 '14 at 16:46
