Hang on pg

@bcardiff
From a nasty puts debugging the call to PQ::Connection.read_next_row_start assigns 'E' instead of 'D' probably (?) in type = soc.read_char

I haven't go any further than this.

require "pg"

`psql -c "DROP DATABASE IF EXISTS issue_db_46"`
`createdb issue_db_46`
`psql -d issue_db_46 -c "CREATE TABLE users (name varchar(50), CONSTRAINT key_name UNIQUE(name));"`
`psql -d issue_db_46 -c "INSERT INTO users (name) VALUES ('test');"`

db = DB.open("postgres://localhost/issue-db-46")

puts "A"

db.query "INSERT INTO users (name) VALUES ($1) RETURNING *", "test" do |rs|
  rs.move_next
end

puts "Z"

db.close

Related to crystal-lang/crystal-db#46 and Crecto/crecto#76.
