Re: How to log quires which are taking time in PostgreSQL 9.1.

set log_min_duration_statement = 300,000

(300,000 ms = 5min)

From the docs:

log_min_duration_statement (integer)

Causes the duration of each completed statement to be logged if the
statement ran for at least the specified number of milliseconds. Setting
this to zero prints all statement durations. Minus-one (the default)
disables logging statement durations. For example, if you set it to
250ms then all SQL statements that run 250ms or longer will be logged.
Enabling this parameter can be helpful in tracking down unoptimized
queries in your applications. Only superusers can change this setting.
