Patch applied. Thanks.
> Hi,
>
> Attached is a patch for JDBC's getColumn() function that was broken /
> flawed in the following ways:
>
> 1. Only returned columns that had a default value defined, rather than all
> columns in a table
> 2. Used 2 * N + 1 queries to find out attributes, comments and typenames
> for N columns.
>
> By using some outer join syntax it is possible to retrieve all necessary
> information in just one SQL statement. This means this version is only
> suitable for PostgreSQL >= 7.1. Don't know whether that's a problem.
>
> I've tested this function with current sources and 7.1.3 and patched both
> jdbc1 and jdbc2. I haven't compiled nor tested the jdbc1 version though, as
> I have no JDK 1.1 available.

> select

> description
> from
> ...
> left outer join col_description(a.attrelid, a.attnum) description
> order by
> c.relname, a.attnum;
>
> (the error was parse error at or near '(') so I had to paste the actual
> code for the col_description function into the left outer join. Maybe

> better SQL statement.

> Please review.
