C tests
-------

Makefile              All C programs are made by doing

                        make <program_name>

makedev               This tests changes to the postgres interface. Make C
                      programs like this:

                        make -f makedev <program_name>
	
pg_submit.c           Prompts for a query (no carriage returns), executes it, 
                      and lets us examine the dbConn and the dbObj. If you
                      enter 'maxrec' it will let you set the number of instances
                      to return (the default is to return everything). If you 
                      enter 'dbconn', it will output the database connector.

                      It calls gdi_print to display the data, which has not been
                      updated yet to output GDI_TURBO array types. Array
                      attributes will very likely have garbage. But at least 
                      it lets us qa the dbObj.

tst_str_arrays.c      Tests dimensioned and undimensioned string arrays.
tst_str_arrays.pq     Creates test_string2, accessed by tst_str_arrays.
tst_str_arrays.dat    Data file for loading data into test_string2.

tst_num_arrays.c      Tests undimensioned numeric arrays (dimensioned numeric
                      arrays are exercised by the pg_dd -i and -f options).
tst_num_arrays.pq     Creates array_num, accessed by tst_num_arrays.c.
tst_num_arrays.dat    Data file for copying data into array_num.

test_conn_twice       Connects to two databases on different PGHOST's and
                      and queries for the database on that host.
