[tests] ProbackupTest::simple_bootstrap and PG9.6

Hello,

Lines 572 to 574 in a2510f5

	# PG 9.6
	elif self.get_version(node) > 90600 and self.get_version(node) < 100000:
	node.safe_psql(

Is this condition self.get_version(node) > 90600 really correct?

Or is it must be ">=90600"?

If I understand correctly the current code will process PG9.6 in the section for PG v15+
