Since the PGADmin4 client timed out when creating the index, you picked my
interest here and i was wondering if the index creation itself had failed...
but:
\d tmp_outpatient_rev
Indexes:
"ui_outprev_ptclaimline" UNIQUE, btree (desy_sort_key, claim_no,
clm_line_num)
"i_outprev_ptclaim" btree (desy_sort_key, claim_no)
So looks like the indices are file. I am pursuing some of the other
recommendations you suggested before.
Thank you,
Laurent.

It would certainly be good to look at psql's \d tmp_outpatient_rev
output to ensure that the index is not marked as INVALID.
