The PostgreSQl 9.3 JDBC driver fails to find foreign tables

От

Дата:
The metadata class for 9.3 JDBC driver is unable to find foreign tables, the
9.2 is working good.

I am using metadata.getTables(catalog, schemaPattern, tableNamePattern,
tableTypes), and the table type does have "FOREIGN TABLE" in the list.

Is anyone else seeing this?

Found the cause, the hashmap values for "FOREIGN TABLE" in
AbstractJdbc2DatabaseMetaData class is getting overwritten by "MATERIALIZED
VIEW" values:

Before
        ht = new HashMap();
        tableTypeClauses.put("FOREIGN TABLE", ht);
        ht.put("SCHEMAS", "c.relkind = 'f'");
        ht.put("NOSCHEMAS", "c.relkind = 'f'");
        tableTypeClauses.put("MATERIALIZED VIEW", ht);
        ht.put("SCHEMAS", "c.relkind = 'm'");
        ht.put("NOSCHEMAS", "c.relkind = 'm'");


After (fix):
        ht = new HashMap();
        tableTypeClauses.put("FOREIGN TABLE", ht);
        ht.put("SCHEMAS", "c.relkind = 'f'");
        ht.put("NOSCHEMAS", "c.relkind = 'f'");
        ht = new HashMap(); // this is the line missing
        tableTypeClauses.put("MATERIALIZED VIEW", ht);
        ht.put("SCHEMAS", "c.relkind = 'm'");
        ht.put("NOSCHEMAS", "c.relkind = 'm'");
