> This chapter lists known peculiarities of the pgsql driver.
Wherever possible, nonstandard driver behavior is hidden by libdbi's
abstractions, but occasionally special considerations must be taken or
extra functionality may be utilized for particular drivers.

> PostgreSQL has no intrinsic concept of unsigned fields (although you
can still use the "OID" type as an unsigned long, or define your own
user-defined unsigned types). User-defined types are not handled
specially. All unrecognized datatypes are preserved as strings.
