There is no need to complicate your Makefile with a custom coverage
target, which is, at least it seems to me, the origin of the problems
you are seeing here. So you could just use the one that Postgres' PGXS
provides. Here is a simple Makefile I have used for coverage testing
with an extension:
https://github.com/michaelpq/pg_plugins/blob/master/decoder_raw/Makefile
If you enforce abs_top_srcdir=$(pwd) with make coverage, or
coverage-html if you want, then both are able to work properly. At
least for me they do.
