Well, if I don't do this it wants to seqscan a table that occupies 350k
pages, instead of pulling a couple thousand rows. I started running it
with the seqscan and it's already taken way longer than it does if I
disable seqscan.

I guess I'll try expanding the statistics.

TIP 9: the planner will ignore your desire to choose an index scan if your
      joining column's datatypes do not match
