Re: PQconnectStart/PQconnectPoll

PQconnectdb is taking too long comparing to mysql and i found out the time is consumed by PQconnectPoll waiting for the socket to be ready for reading/writing

What's "too long"?

I cannot use persistent connections. I must open/close a connection anytime I want to insert something new.

If you mean that you intend to open a new connection, do a single INSERT, and close the connection - your performance will be awful.

If your app can't use persistent or pooled connections, use PgBouncer as an external connection pool. Have your app connect to PgBouncer, and PgBouncer connect to PostgreSQL.
