It is time for you to learn better, right now.
7.4.2 is old and has numerous known bugs. There is a valid argument
for sticking to the 7.4.* series, having to do with avoiding any
possible application-compatibility issues for apps that've only been
tested with 7.4.*, but there is no reason other than vendor laziness
to still be on a two-year-old subrelease in the 7.4.* series.
7.4 is currently at 7.4.11 (by Tuesday it will be 7.4.12) and there
are a significant number of security holes and risk-of-data-loss bugs
fixed in those updates. See the release history at
http://developer.postgresql.org/docs/postgres/release.html
and then ask yourself if you still trust your Linux vendor's judgment
so much.
Or you can "learn better" the hard way, by losing data. Your choice.
