Indexes:

Foreign-key constraints:

"katello_content_facet_errata_errata_id" FOREIGN KEY (erratum_id) REFERENCES katello_errata(id)

So, I created an index:

foreman=# create index "katello_content_facet_errata_caid" ON "katello_content_facet_errata" using btree(content_facet_id);
CREATE INDEX
foreman=# \d "katello_content_facet_errata"

Indexes:
"katello_content_facet_errata_pkey" PRIMARY KEY, btree (id)
"katello_content_facet_errata_eid_caid" UNIQUE, btree (erratum_id, content_facet_id)

Foreign-key constraints:

"katello_content_facet_errata_errata_id" FOREIGN KEY (erratum_id) REFERENCES katello_errata(id)

And now:

foreman=# explain analyze SELECT "katello_content_facet_errata".* FROM "katello_content_facet_errata" WHERE "katello_content_facet_errata"."content_facet_id" IN (8984, 9436, 9384, 9215, 9214, 9213, 9212, 9386, 9383, 8610, 9104, 8607, 8606, 8604, 13994, 9179, 8806, 16912, 9919, 8694, 8695, 8696, 8697, 8698, 9190, 8803, 8804, 8617, 9180, 8917, 9025, 8577, 9388, 9586, 13983, 10166, 14183, 11828, 14166, 14170, 14175, 13938, 13984, 14008, 13982, 16486, 13899, 10160, 10169, 10159);
