Cool, thanks! Attached is an updated patch for the module. Backward
compatibility has been brought back, and the module has been tested on
PostgreSQL versions 8.4.0 and 9.1devel.
However, there are a couple minor caveats:
* The last test, relocatable, fails (and should fail) on pre-9.1
because it's a test related to the new extension interface.
* init.sql is rather hacky in how it caters to both the old extension
system and the new one:
\set ECHO none
SET client_min_messages = fatal;
CREATE EXTENSION json;
\i json--0.1.sql
SET client_min_messages = warning;
...
RESET client_min_messages;
\set ECHO all
It would be nice if I could make a Makefile conditional that skips the
relocatable test and loads init-pre9.1.sql if the new extension
interface isn't available. Is there a Makefile variable or something
I can use to do this?
Also, should uninstall_json.sql be named something else, like
json--uninstall--0.1.sql ?
Thanks,
