The discussion was focused on the ability of the server to return the
alias of a table as well as the base table name. Because getColumnName
will return "b" for "SELECT a AS b FROM c AS d" we have decided that
getTableName should return "d" instead of "c". Right now the server will
tell the driver about a, b, and c, but not d. So we're sort of waiting
for the server to return "d", but no plans have been made to extend the
protocol to include this information at this point. So you'll have to
keep waiting or use PGResultSetMetaData.getBaseTableName to return "c"
instead of "d".
