rails 3.0.3 postgresql_adapter does not work with postgres pure ruby drivers anymore
Reported by Edouard de Castro | December 13th, 2010 @ 04:00 PM
In active record 3.0.3 postgresql_adapter doesn't work with postgres-pr gem anymore, as it only requires 'pg' (unlike on 2.3.8).
adding back (like in rails 2.3.8)
begin
require_library_or_gem 'pg'
rescue LoadError => e
begin
require_library_or_gem 'postgres'
class PGresult
alias_method :nfields, :num_fields unless self.method_defined?(:nfields)
alias_method :ntuples, :num_tuples unless self.method_defined?(:ntuples)
alias_method :ftype, :type unless self.method_defined?(:ftype)
alias_method :cmd_tuples, :cmdtuples unless self.method_defined?(:cmd_tuples)
end
rescue LoadError
raise e
end
end
in postgresql_adapter.rb just before module Active Record declaration
and removing:
@@@require 'pg'@@@
from postgresql_connection method
fixes the problems...
But why was this changed in the first place? Only Pg module/gem should be used? (postgres-pr hasn't been updated since dec 2009...) OK, but then it shouldn't be mentioned that the adapter is also working with the pure ruby driver!?
(p.s. 'also had problems with - in initialize method - getting the TimeZone (w. pg 8.4), added rescue nil ...)
