Checking the current sources, git history, and various older commits, I
did not find where HSTORE_IS_HSTORE_NEW was ever defined. I expect it
was defined at some point, but I checked back as far as 9.0 (where the
current contrib/hstore was originally committed) and did not see it.
Where did you find this, and can we add a code comment? This one #ifdef
is the only line in the entire repository where this label is used,
making it hard to check if changing from #if was the right decision.
The check on HSTORE_IS_HSTORE_NEW goes back at least as far as 2006,
suggesting it was needed for migrating from some version pre-9.0, making
me wonder if anybody would need this in the field. Should we drop
support for this? I don't have a strong reason to advocate dropping
support other than that this #define appears to be undocumented.
