Pg is the Ruby interface to the {PostgreSQL RDBMS}[http://www.postgresql.org/].
It works with {PostgreSQL 9.2 and later}[http://www.postgresql.org/support/versioning/].
A small example usage:
#!/usr/bin/env ruby
require 'pg'
# Output a table of current connections to the DB
conn = PG.connect( dbname: 'sales' )
conn.exec( "SELECT * FROM pg_stat_activity" ) do |result|
puts " PID | User | Query"
result.each do |row|
puts " %7d | %-16s | %s " %
row.values_at('procpid', 'usename', 'current_query')
end
end

PostgreSQL Cursor is an extension to the ActiveRecord PostgreSQLAdapter for
very large result sets. It provides a cursor open/fetch/close interface to
access data without loading all rows into memory, and instead loads the result
rows in 'chunks' (default of 1_000 rows), buffers them, and returns the rows
one at a time.

This is the MySQL API module for Ruby. It provides the same functions for Ruby
programs that the MySQL C API provides for C programs.
This package is offered as gem for easy installation using RubyGems. It wraps
unmodified tmtm's mysql-ruby extension into a proper gem.
Please note that tmtm (Tomita Mashahiro) has deprecated development of this
extension and only update it for bug fixes.
