PostgresUpdater::dropIndex	(	$	table,
		$	index,
		$	patch = `''`,
		$	fullpath = `false`
	)		`[protected]`

Drop an index from an existing table.

Parameters:

string	$table	Name of the table to modify
string	$index	Name of the index
string	$patch	Path to the patch file
bool	$fullpath	Whether to treat $patch path as a relative or not

Returns:: bool False if this was skipped because schema changes are skipped

PostgresUpdater::getCoreUpdateList ( ) [protected]

Todo:: FIXME: Postgres should use sequential updates like Mysql, Sqlite and everybody else.

It never got refactored like it should've.

Returns:: array

Reimplemented from DatabaseUpdater.

Definition at line 41 of file PostgresUpdater.php.

PostgresUpdater::getOldGlobalUpdates ( ) [protected]

Before 1.17, we used to handle updates via stuff like $wgExtNewTables/Fields/Indexes.

This is nasty :) We refactored a lot of this in 1.17 but we want to remain back-compatible for a while. So load up these old global-based things into our update list.

Returns:: array

Reimplemented from DatabaseUpdater.

PostgresUpdater::renameIndex	(	$	table,
		$	oldIndex,
		$	newIndex,
		$	skipBothIndexExistWarning = `false`,
		$	patch = `false`,
		$	fullpath = `false`
	)		`[protected]`

Rename an index from an existing table.

Parameters:

string	$table	Name of the table to modify
string	$oldIndex	Old name of the index
string	$newIndex	New name of the index
	$skipBothIndexExistWarning	Boolean: Whether to warn if both the old and the new indexes exist.
string	$patch	Path to the patch file
bool	$fullpath	Whether to treat $patch path as a relative or not
