Neat, I hadn't heard of it before ;)

The version in PGDG has the "amkeytype" issue, so I compiled,

I got this:

[pryzbyj@database pg_catcheck]$ ./pg_catcheck ts
notice: pg_shdepend row has invalid classid "2613": not a system catalog OID
row identity: dbid="16402" classid="2613" objid="1086583699" objsubid="0" refclassid="1260" refobjid="16384"
deptype="o"
notice: pg_shdepend row has invalid classid "2613": not a system catalog OID
row identity: dbid="16402" classid="2613" objid="1086583701" objsubid="0" refclassid="1260" refobjid="16384"
deptype="o"
[...]

notice: pg_depend row has invalid objid "1124153791": no matching entry in pg_class
row identity: classid="1259" objid="1124153791" objsubid="0" refclassid="1259" refobjid="1064197368" refobjsubid="1"
deptype="a"

progress: done (294 inconsistencies, 0 warnings, 0 errors)

.. those are the only two problem oids:
[pryzbyj@database pg_catcheck]$ time ./pg_catcheck ts 2>&1 |grep -Evw '2613|1259'
progress: done (264 inconsistencies, 0 warnings, 0 errors)
