Specifically, I'm wondering if I should do the ANALYZE before or after I recreate the indexes, or whether it matters.
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.
