What
Expose the 4-byte type-specific type modifier on the Column struct
Why
I would like access type modifiers for prepared statement columns. E.g. for a numeric column I would like to get the numeric precision and scale. For a varchar column I would like to get the varchar length limit.
Context
This is an extension of #1084 where other table and column OIDs were exposed in Column, and exposing type modifiers was noted as a possibility.
