You can use pgmonitor to visually see general load and check if there is
any contention. Your sample queries were all SELECTs but the data has
to be getting in there somehow.
What's the relationship between the process that issues the queries and
the database machine? Could there be any latency between the two?
Individual queries could run quickly but if the requester takes a while
to retrieve the request results before submitting a subsequent query,
that can result in problems?
Without index, table size and sample distribution information (or
explain verbose output), it is difficult to say if any one query could
be made to execute faster.
