[PATCH] New PDO methods for PostgreSQL driver

Hi. I developed some patches for PDO/Postgresql driver in order to add some useful methods that were available in the original pgsql driver. The attached patches apply on 5.3.2 and svn 5.3.x. If needed, i have patches also for 5.2.x. Please comment and tell me improvements or tips. Thank you in advance, Denis Gasparin Documentation of the added methods follows: pgsqlIsInTransaction() It uses the native Postgresql functions to check transaction status. It returns one of the following status codes: * PDO::PGSQL_TRANSACTION_IDLE: connection in idle status * PDO::PGSQL_TRANSACTION_ACTIVE: connection is executing a command * PDO::PGSQL_TRANSACTION_INTRANS: connection is idle in a valid transaction block * PDO::PGSQL_TRANSACTION_INERROR: connection is idle, in a failed transaction block * PDO::PGSQL_TRANSACTION_UNKNOWN: connection is in a bad status pgsqlCopyFromArray($table,Array $data,$delimiter,$null, Array $fields) It uses the native Postgresql copy construct to append $data to $table. It returns boolean. Parameters: * (mandatory) $table: table to append data to * (mandatory) $data: Array of rows with data in table field order (or as specified in the $fields array). Fields must be separated by $delimiter or by postgresql standard \t) * $delimiter: alternative delimiter to use in place of the standard postgres delimiter ("\t") * $null: alternative string to use as null value. Default is "\N" * $fields: array with table fields that are specified in $data parameter pgsqlCopyFromFile($table,$filename,$delimiter,$null,$fields) It uses the native Postgresql copy construct to append $filename contents to $table. It returns boolean. Parameters: * (mandatory) $table: table to append data to. * (mandatory) $filename: file with contents to append to $table. See Postgresql documentation for the format. * $delimiter: alternative delimiter to use in place of the standard postgres delimiter ("\t") * $null: alternative string to use as null value. Default is "\N" * $fields: array with table fields that are specified in $filename file pgsqlCopyToArray($table,$delimiter,$null,$fields) It uses the native Postgresql copy construct to retrieve $table contents and store them to an array. It returns an array of rows or false in case of problems. The format of the rows into the array is indicated in the $delimiter, $null and $fields parameters. Parameters: * (mandatory) $table: table to retrieve data from. * $delimiter: alternative delimiter to use in place of the standard postgres delimiter ("\t") * $null: alternative string to use as null value. Default is "\N" * $fields: array with table fields to include in the row of the array. pgsqlCopyToFile($table,$filename,$delimiter,$null,$fields) It uses the native Postgresql copy construct to retrieve $table contents and store them into a file. It returns boolean. The format of the rows stored into the file is indicated in the $delimiter, $null and $fields parameters. Parameters: * (mandatory) $table: table to retrieve data from. * (mandatory) $filename: file where to store the contents of the table * $delimiter: alternative delimiter to use in place of the standard postgres delimiter ("\t") * $null: alternative string to use as null value. Default is "\N" * $fields: array with table fields to include in the row of the array.
