could not go to sleep, so PR instead.. insomnia is a bitch ^^

This adds a version warning for postgis<3.5

Yes, it might be a bit too early too tell, but all signs point to older versions being buggy.
Lets keep #1651 open to keep tabs on weather the upstream issue changes.

Seems new warning needs to be removed either in test.sh

martin/tests/test.sh

Lines 186 to 189 in e024ff0

	# Older versions of PostGIS don't support the margin parameter, so we need to remove it from the log
	remove_line "$LOG_FILE" 'Margin parameter in ST_TileEnvelope is not supported'
	remove_line "$LOG_FILE" 'Source IDs must be unique'
	remove_line "$LOG_FILE" 'PostgreSQL 11.10.0 is older than the recommended 12.0.0'
