	The default for %f is 6 digit precision. So with doubles we are
	losing 9! But well, it is ok. If who use the library wants
	another representation, she just have to get the value and
	convert it to whatever she wants. Anyway, we should document this
	'feature'.

	Next:

		-By watching in the logs what psql does and the source
		code of it, I will soon be able to get more accurate
		values for the scale of a decimal(n,p), the maximum size
		of a varchar and the like. When I get it, I'll improve
		that portion of the postgresl provider.

		-I could do, if you want, a modified version of
		display_data_model() (testing/models.c) that also shows
		the column names. So every provider can use it to test
		its recordsets.

		-Also, I will be adding a new type (first of all I'll
		modify the IDL and send it to the list to get feedback)
		from time to time.

	Is there any other thing you want me to do in libgda?

	Bye!
