The relevant settings are described here:
http://www.postgresql.org/docs/9.0/interactive/runtime-config-wal.html#RUNTIME-CONFIG-REPLICATIONhttp://www.postgresql.org/docs/9.0/interactive/runtime-config-wal.html#RUNTIME-CONFIG-STANDBY
The ones that you might want to look at are:
vacuum_defer_cleanup_age
max_standby_archive_delay
max_standby_streaming_delay
Leaving some gaps for "catch up time" between long-running requests
can help prevent cancelations, since the lag can otherwise
accumulate.
