+### Troubleshooting FAQ
+
+#### python test failures
+1. Test failure reason like 
+```
+testgres.exceptions.QueryException ERROR:  could not open extension control file "/home/avaness/postgres/postgres.build/share/extension/amcheck.control": No such file or directory
+```
+
+*Solution*: you have no `<postgres_src_root>/contrib/` extensions installed
+
+```commandline
+cd <postgres_src_root>
+make world install
+```
+
+2. Test failure
+
+```
+FAIL: test_help_6 (tests.option.OptionTest)
+```
+
+*Solution*: you didn't configure postgres build with `--enable-nls` 
+
+```commandline
+cd <postgres_src_root>
+make distclean
+<your-./configure-cmdline> --enable-nls
+```
