PG strings in arrays are casted to UUIDs when not needed #1086

I'm trying to migrate from MRI and pg to JRuby and AR-JDBC.

Suppose I have a column

my_string character varying,

for the model Test. Additionally, my_string can sometimes contain strings which match the UUID format.

The problem: when I do

Test.where(my_string: ["ec984527-9a13-3049-acd9-f862108257e4",
  "d4c22210-1824-37b1-bbe8-54558b2613dc",
  "dd7400e5-b306-39a5-b001-32af27d42a78"])

I get

ActiveRecord::JDBCError: org.postgresql.util.PSQLException: ERROR: operator does not exist: character varying = uuid
  Hint: No operator matches the given name and argument types. You might need to add explicit type casts.

This was working on MRI with pg.
