linkend="wal"><acronym>WAL</acronym></link>, or a custom implementation.

If <acronym>WAL</acronym> is chosen, either <link

linkend="generic-wal">Generic WAL Records</link> can be used,

or a new type of <acronym>WAL</acronym> records can be implemented.

Generic WAL Records are easy, but imply higher WAL volume.

Implementation of a new type of WAL record

currently requires modifications to core code (specifically,

<filename>src/include/access/rmgrlist.h</filename>).

or a <link linkend="custom-rmgr">Custom WAL Resource Manager</link> can be

implemented.
