Right. Although you can mostly fight it there using USE_MODULE_DB.
The attached patch that replaces all hardcoded occurrences of
'contrib_regression' with current_database(). Allowing a make -j32 -s
installcheck in contrib to succeed in less than 4 seconds...
That's not particularly pretty, especially in the CREATE SERVER calls
(via DO ... EXECUTE), but imo worth it given the timesavings.
What's your thought on that one?

Unfortunately I don't think you can make .NOTPARALLEL work across more
than one directory when using recursive make :(. At least I don't know
how.
