An indexed boolean field?
Hopefully, ftindex is false for very few rows of the table?
Try changing the ftindex to be a partial index, so only index the false
values. Or don't index it at all.
Split the table up into smaller pieces.
Don't use an UPDATE statement. Keep a second table, and insert records
into it when you would have updated previously. If a row is not found,
you know that it has ftindex=true. That way, you'll never have row
versions building up in the main table, which you'll still get even if
you VACUUM.
