Thanks for your response! I actually created a new database with initdb and started it without tuning anything just prior to running the installcheck each time. However, I did start fresh and try just the make check anyway: cd /tmp/postgresql-9.5.9/ ./configure --with-segsize=10 --with-blocksize=32 --with-pam --with-libraries=/usr/local/lib --with-includes=/usr/local/include make -j8 cd contrib/postgres_fdw/ gmake gmake check And it did fail again: gmake: *** [../../src/makefiles/pgxs.mk:280: check] Error 1 The regression.diffs file was identical to what I previously attached (besides the timestamps). Is there an issue with my procedure, maybe? (Though the same procedure worked with 9.4.4 and 9.4.9.) > On Sep 20, 2017, at 1:00 PM, Tom Lane <tgl@xxxxxxxxxxxxx> wrote: > > Natalie Wenz <nataliewenz@xxxxxxxxxxx> writes: >> I have a server that has 9.4.4 with the postgres_fdw module successfully running for the past couple of years. I am looking to update it, so I'm testing the procedure on a test server, and have been running into trouble. Out of curiosity, I tried installing it with 10beta4, but the gmake installcheck failed. So I tried with 9.6.2 (because it happened to be on the machine) and it still failed. I tried 9.6.5--and it also failed. > >> Note that the installation doesn't seem to have any issue, just the installcheck. Is this a known issue? Is it just a matter of the regression tests lagging behind, or should I be concerned? The regression.diffs files are not identical between versions, but they only seem to contain query plans with differences. > > If you're running with any non-default planner settings in your > installation, this would likely be unsurprising.
