Hi, this is a bug in the commit 0d831389749a3baaced7b984205b9894a82444b9 .

It allows vucuum freeze to be skipped and inversely lets regular
vacuum wait for lock. The attched patch fixes it.


In table_recheck_autovac, vacuum options are determined as following,

 >      tab->at_vacoptions = VACOPT_SKIPTOAST |
 >              (dovacuum ? VACOPT_VACUUM : 0) |
 >              (doanalyze ? VACOPT_ANALYZE : 0) |
!>              (wraparound ? VACOPT_NOWAIT : 0);

The line prefixed by '!' looks inverted.

Thanks, it is obvious once you see it!
