You need to update to 7.4.18 or whatever the last version was. 7.4.2
has known data eating bugs, and if you value your data even a little,
you should update. this is a relatively painless update not requiring
a dump / restore.

I've had large tables take well over 10 minutes on 7.4 to reindex.
That's not necessarily a sign of a problem. How many rows does this
table have? Do you get any kind of error message or the database just
never returns. Have you tried vacuum full on this table instead? Do
the logs say anything about the reindex operation getting an error
etc???

Is it really not executing? Is it simply returning without a notice,
or hanging?

You would do well to consider a migration to 8.2.5 or 8.3 when it
comes out of beta / RC status. 7.4.x is getting rather old, and the
8.x series (8.0, 8.1, 8.2, and now 8.3) have each had major
improvements in speed.
