Selecting a constant string or concatenated columns from postgres
using jisql (xigole), I get heap overflow.

select 'X' AS XXX from . . . .
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

This discussion seems to say this is a postgres JDBC bug:

I tried going back to the last rev 7 JAR, and these queries work,
albeit with 65K column widths.  Something is seriously wrong in this
method, if it cannot size a three byte label or a one byte constant
