Ok.
+ int vmaj = 0,
+ vmin = 0,
+ vrev = 0;
+ const char *amcheck_version = pstrdup(PQgetvalue(result, 0, 1));
+
+ sscanf(amcheck_version, "%d.%d.%d", &vmaj, &vmin, &vrev);
The pstrdup is unnecessary but harmless.

Ok.

It appears you still create a new table, bttest_unique, rather than using the existing table int4tbl. That's fine.

You have borrowed the existing tests but forgot to change their names. (The last line of each check is the test name,
suchas 'pg_amcheck smoke test --parent-check'.) Please make each test name unique.
> - added test contrib/amcheck/t/004_verify_nbtree_unique.pl it is more extensive test based on opclass damage which
wasintended to be main test for amcheck, but which I've forgotten to add to commit in v5.
> 005_opclass_damage.pl test, which you've seen in v5 is largely based on first part of 004_verify_nbtree_unique.pl
(withthe later calling pg_amcheck, and the former calling bt_index_check(), bt_index_parent_check() )
Ok.
> - added forgotten upgrade script amcheck--1.3--1.4.sql (from v4)
Ok.
