Yeah, sorry, I meant `make`.

I still see this pattern a *lot*; I removed it from PL/Proxy last week. The attached tarball demonstrates it:

    > make
    sed 's,MODULE_PATHNAME,$libdir/sql/exttest,g' sql/exttest.sql.in >sql/exttest.sql
    make: *** No rule to make target `exttest.so', needed by `all'.  Stop.

So MODULE_PATHNAME is replaced with $libdir/sql/exttest rather than $libdir/exttest. Maybe that should not be fixed,
butthere are a *lot* of extensions out there using this approach (copied from contrib, which used it for years, albeit
withoutthe .sql.in files in a subdirectory). 

So perhaps DATA_built is to be removed from pgxs.mk? And if so, is the idea then that one should just put the module
namein the .sql file, rather than MODULE_PATHNAME in a .sql.in file? 

Best,
