    pg: respect format codes from Bind message when sending results · 696a50ed
    Konstantin Shaposhnikov 提交于
    From https://www.postgresql.org/docs/9.1/static/protocol-message-formats.html:
    
      Bind (F)
    
      ...
    
      After the last parameter, the following fields appear:
    
      Int16
    
        The number of result-column format codes that follow (denoted R
        below). This can be zero to indicate that there are no result
        columns or that the result columns should all use the default
        format (text); or one, in which case the specified format code is
        applied to all result columns (if any); or it can equal the actual
        number of result columns of the query.
    
      Int16[R]
    
        The result-column format codes. Each must presently be zero (text)
        or one (binary).
    
    Also fix testBinaryTypes test:
    
    - force binary by setting prepareThreshold to -1
    - handle REAL type as float
    
    Without the fix the corrected test testBinaryTypes fails:
    
      05:25:02 21:55:02.666 org.h2.test.unit.TestPgServer Expected: 12345678 actual: 825373492
      Exception in thread "main" java.lang.AssertionError: Expected: 12345678 actual: 825373492
