System db fault in pg connection driver when use group/by

[majioa]

I have the following error when issuing group by operation in pg connection:

> self.all.group(:inn)
=> (pry) output error: java.lang.NoSuchMethodError: org.jruby.RubyEncoding.newEncoding(Lorg/jruby/Ruby;Lorg/jcodings/Encoding;)Lorg/jruby/RubyEncoding;

That is the SQL query:

> self.all.group(:inn).to_sql
=> "SELECT \"organizations\".* FROM \"organizations\" GROUP BY \"organizations\".\"inn\""

and also I've tried it with plain sql call with the same result:

> self.connection.execute( "SELECT \"organizations\".* FROM \"organizations\" GROUP BY \"organizations\".\"inn\"")
Java::JavaLang::NoSuchMethodError: org.jruby.RubyEncoding.newEncoding(Lorg/jruby/Ruby;Lorg/jcodings/Encoding;)Lorg/jruby/RubyEncoding;
from org.jruby.pg.Connection.newPgErrorCommon(Connection.java:1434)

This looks like the same bug as #32

I guess this has been fixed with commit 9cc73de. Maybe @majioa could confirm this, otherwise it would be hard to reproduce this with this amount of information.

@qnet-herwin i can't reproduce or confirm it for now, sorry, because currently the project doesn't use pg-jruby

I just got this error with pg-jruby 0.17.1.

[donv]

I can confirm this bug has been fixed in jruby-pg 0.1

[majioa]

@donv 0.1?

[donv]

Yes @majioa , this gem has changed its name from pg-jruby to jruby-pg and started the versioning from 0.1.
