Add the primary_keys and primary_key_sequences instance variables, so we can get the correct return values for inserted rows.

Connects to the database. In addition to the standard database options, using the :encoding or :charset option changes the client encoding for the connection.
# File lib/sequel/adapters/postgres.rb, line 196 196: def connect(server) 197: opts = server_opts(server) 198: conn = Adapter.connect( 199: (opts[:host] unless blank_object?(opts[:host])), 200: opts[:port] || 5432, 201: nil, '', 202: opts[:database], 203: opts[:user], 204: opts[:password] 205: ) 206: if encoding = opts[:encoding] || opts[:charset] 207: if conn.respond_to?(:set_client_encoding) 208: conn.set_client_encoding(encoding) 209: else 210: conn.async_exec("set client_encoding to '#{encoding}'") 211: end 212: end 213: conn.db = self 214: conn.apply_connection_settings 215: conn 216: end
Return instance of Sequel::Postgres::Dataset with the given options.
# File lib/sequel/adapters/postgres.rb, line 219 219: def dataset(opts = nil) 220: Postgres::Dataset.new(self, opts) 221: end
Execute the given SQL with the given args on an available connection.
# File lib/sequel/adapters/postgres.rb, line 224 224: def execute(sql, opts={}, &block) 225: check_database_errors do 226: return execute_prepared_statement(sql, opts, &block) if Symbol === sql 227: synchronize(opts[:server]){|conn| conn.execute(sql, opts[:arguments], &block)} 228: end 229: end
Insert the values into the table and return the primary key (if automatically generated).
# File lib/sequel/adapters/postgres.rb, line 233 233: def execute_insert(sql, opts={}) 234: return execute(sql, opts) if Symbol === sql 235: check_database_errors do 236: synchronize(opts[:server]) do |conn| 237: conn.execute(sql, opts[:arguments]) 238: insert_result(conn, opts[:table], opts[:values]) 239: end 240: end 241: end
