- -c
- Check connection parameters, set if uninitialized, and exit
- -d
- Set from default settings and exit
- Overwrite current settings if initialized
- -g

- --quiet

Parameters:
- driver=name
- Name of database driver
- Options: sqlite, pg
- database=name
- Name of database
DESCRIPTION
t.connect allows the user to set the temporal GIS database connection.
NOTES
Values are stored in the mapset's VAR file;
the connection is not tested for validity.
The -d flag will set the default TGIS connection parameters.
A sqlite3 database "tgis.db" will be created in the PERMANET directory of the current location.
The -p flag will display the current TGIS connection parameters.
The -pg flag will display the current TGIS connection parameters using shell style.
The -c flag will silently check if the TGIS connection parameters have
been set, and if not will set them to use GRASS's default values.
Note
The default TGIS database of type sqlite3 is located in the PERMANENT mapset directory.
Temporal GIS content from all created mapsets will be stored here. In case
you have thousends of maps to register in the temporal database or you need concurrent read
and write access in the TGIS database, consider to use a postgresql database instead.
SQLite
t.connect driver=sqlite database='$GISDBASE/$LOCATION_NAME/PERMANENT/tgis.db'
t.connect -p
t.info -s
The SQLite database is created automatically when used the first time.
PostgreSQL
In case you use a postgresql database, you will need to specify the TGIS database connection
for each mapset.
t.connect driver=pg database="dbname=grass_test user=soeren password=abcdefgh"
t.connect -p
t.info -s
