Hi,

I guess its simply because String fields in postgres can not be larger than 1 GB, long type could represent length values far beyond this limit surpassing postgres limits.

Hi,
         I have question about statement.Some method that provided by JAVA API were not implemented in postgresql jdbc.
I focus on method named ‘setCharacterStream(int parameterIndex, Reader value, long length)’,it was not implemented,but
‘setCharacterStream(int i, java.io.Reader x, int length)’ was implemented.The different between them is the type of the third
parameter. I don’t know why the first method was not implement,because the column can not store the ‘value’ whoes length
is the ‘length’? Or other reason? Thank you.
