Comment 1 for bug 1937294

The following pgtap tests fail when run on PostgreSQL version 12 through 14:

t/authority-update-bib-propagation.pg (Wstat: 0 Tests: 9 Failed: 4)
  Failed tests: 1-3, 7
t/lp1501781-unaccent_and_squash.pg (Wstat: 0 Tests: 18 Failed: 2)
  Failed tests: 7, 12
t/lp1731960_test_preserving_bookbag_entries.pg (Wstat: 0 Tests: 2 Failed: 1)
  Failed test: 1
t/regress/lp1379815_vl_import_item_stat_cats.pg (Wstat: 0 Tests: 1 Failed: 1)
  Failed test: 1
live_t/0824.item_import_defaults.pg (Wstat: 0 Tests: 1 Failed: 1)
  Failed test: 1
live_t/0847.auth_overlay_generator.pg (Wstat: 0 Tests: 1 Failed: 1)
  Failed test: 1
live_t/lp1145213_test_func_asset.merge_record_assets.pg (Wstat: 0 Tests: 5 Failed: 1)
  Failed test: 1

A subset of the above tests fail on PostgreSQL 11, but the above list includes all of the tests that also fail on Pg 11.

Fixing the Evergreen code so that these tests succeed on PostgreSQL versions 11 through 14 and continue to work on PostgreSQL 10 would be the logical next step in getting Evergreen working on more recent PostgreSQL version.
