◆ getCoreUpdateList()

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

◆ getOldGlobalUpdates()

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

Rename an index from an existing table.

Parameters
string$tableName of the table to modify
string$oldIndexOld name of the index
string$newIndexNew name of the index
bool$skipBothIndexExistWarningWhether to warn if both the old and the new indexes exist.
string$patchPath to the patch file
bool$fullpathWhether to treat $patch path as a relative or not
Returns
bool False if this was skipped because schema changes are skipped
