At the moment it does not matter --- ANALYZE computes statistics for
each column of a table regardless of what indexes exist.

There has been some talk of trying to compute statistics for the
contents of functional indexes.  Also, if we ever do anything about
computing multicolumn correlation statistics, we'd likely choose which
ones are worth computing based on the presence of multicolumn indexes.
So if you want to future-proof your code I'd recommend recreating the
indexes before you ANALYZE.

Thanks, Tom (and everyone else who replied).


I'm already recreating the indices prior to the VACUUM ANALYZE, since this
puts the database back in a more usable state faster than doing the
VACUUM first.  It's good to know that it will probably be the proper way
to do things in the future as well.
