RowDescription (B)
Byte1('T')
Identifies the message as a row description.
Int32
Length of message contents in bytes, including self.
Int16
Specifies the number of fields in a row (can be zero).
Then, for each field, there is the following:
String
The field name.
Int32
If the field can be identified as a column of a specific table, the object ID of the table; otherwise zero.
Int16
If the field can be identified as a column of a specific table, the attribute number of the column; otherwise zero.
Int32
The object ID of the field's data type.
Int16
The data type size (see pg_type.typlen). Note that negative values denote variable-width types.
Int32
The type modifier (see pg_attribute.atttypmod). The meaning of the modifier is type-specific.
Int16
The format code being used for the field. Currently will be zero (text) or one (binary). In a RowDescription returned from the statement variant of Describe, the format code is not yet known and will always be zero.
