More on this: the problem appears to be that the symbols for hstore are
loaded only if I've just just created the extension in that database:
postgres=# create database plperlh
postgres-# ;
CREATE DATABASE
postgres=# \c plperlh;
You are now connected to database "plperlh" as user "josh".
plperlh=# create extension plperl;
CREATE EXTENSION
plperlh=# create extension hstore;
CREATE EXTENSION
plperlh=# create extension hstore_plperl;
CREATE EXTENSION
plperlh=#
plperlh=# \c postgres
You are now connected to database "postgres" as user "josh".
postgres=# create extension hstore_plperl;
