[postgis-users] postgis-1.5.4 deprecated function in postgresql-9.1.4?

[Jason Mahony]

I suppose I should be more clear with my question.

These errors are keeping me up at night. Are they safe to ignore? I'm speculating that lwhistogram2d functions were deprecated in postgres-9.1.4. Or am I way off base here? Thanks for any help.
