What's a good way for me to create a self-contained test case. AFAIU the only way to make these test cases more self-contained would be to inline the second table and its index. How do you create an index to an inlined table of values?
Or perhaps I could send over a dump of a subset of the data?
Yes, I am fairly sure that I am running 9.4.4:
$ psql --version
psql (PostgreSQL) 9.4.4
# select version();
version
-----------------------------------------------------------------------------------
PostgreSQL 9.4.4 on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 5.1.0, 64-bit
(1 row)
Thanks for the help,
Gideon.

FWIW, I couldn't reproduce the described behavior. Can you provide a
self-contained test case? Are you sure your server is 9.4.4?
