Postgres driver.
This driver was originaly written by Alex Shevlakov using dbf driver
(PostgreSQL driver forked from DBF driver by Radim Blazek).
DBF driver was not good starting point, so I (R. Blazek) have rewritten it again
using ODBC, postgres driver and adding new code.
Driver supports only some field types, other types are ignored and warning is printed
by G_warning().
FIELD TYPES:
Field type code may change. See for example
http://developer.postgresql.org/cvsweb.cgi/pgsql-server/src/include/catalog/pg_type.h
Because of this, type codes must be read from server when database is opened.
Check also for PostgreSQL data types for defining them in GRASS:
/usr/include/pgsql/server/catalog/pg_type.h
Supported types in ./globals.h:
(http://www.postgresql.org/docs/8.2/interactive/datatype.html)
DB_C_TYPE_INT:
bit, int2, smallint, int4, int, integer, int8, bigint, serial, oid
DB_C_TYPE_DOUBLE:
float4, real, float8, double precision, numeric, decimal
DB_C_TYPE_STRING:
character, char, character varying, varchar, text, bool, boolean
DB_C_TYPE_DATETIME:
date, time, timestamp
