unrecognized configuration parameter "custom_variable_classes"

Question

I get this message after a system update:

unrecognized configuration parameter "custom_variable_classes" in file "/var/lib/pgsql/data/postgresql.conf" line 501

Are custom variable classes not supported any more?

Answer 1

Since version 9.2 this statement is not needed any more:

Just remove or uncomment the line:

#custom_variable_classes = 'foo'             # list of custom variable class names
foo.bar=0
