Postgres EPSG factory won't work against Postgres 8.3
-----------------------------------------------------
Key: GEOT-2363
URL: http://jira.codehaus.org/browse/GEOT-2363
Project: GeoTools
Issue Type: Bug
Components: core referencing
Affects Versions: 2.5.3
Reporter: Andrea Aime
Assignee: Martin Desruisseaux
Fix For: 2.5.4
Most prepared statements in DirectEpsqFactory and AuthorityCodes won't work
against PostgreSQL 8.3 due to a type mismatch: the official EPSG database sql
script creates primary keys (xxx_code) as integer columns, but the statements
are prepared with setString instead.
This mismatch usually just disables index usage (on most databases) as it
forces the integer column to be "promoted" to a string, but in the case of 8.3
it actually triggers the following error:
{code}
...
Caused by: org.postgresql.util.PSQLException: ERROR: operator does not exist:
integer = character varying

{code}
The fix is easy, the keys are actually numbers, so using setInt(index,
Integer.valueOf(code)) makes the postgres factory work again
