DatabaseMetaData.getColumns is missing the 'COLUMN_SIZE' in the result set. This is also screwing
up the order in which other fields are returned. 

Below is the column size returned by postgres for different data types. Though its specific
to the data, I am just adding it here
{code}
int8 : 19   (this is a bigint column)
bool:1
date:13
float8:17  (this is a double column)
float8:17 (this is a float column)
int4 : 10
time:15
timestamp : 29
varchar : 50
{code}

Below are few things an analytic tool might use which are currently not working because of
this :
{code}
DECIMAL_DIGITS : 9
NULLABLE : 11
REMARKS : 12
{code}
