Sure, to some extent, but ideally you wouldn't use it in a recurring
fashion but only as an emergency solution out of a really serious bloat
problem (so it's not something you should have impacting your production
in a recurring fashion); also, performance should improve for the system
overall, comparing to the state before compacting the table.

I suggest you try pg_squeeze (a single run of it in a table, not
scheduled runs) and report back how the system performs for you in the
period when it is executing.  I expect that the impact of REPACK is
going to be largely the same as that of pg_squeeze, because the
implementation is very similar.
