Okay, I added "Lakshmi N" because of this commit which is linked to from
the release notes:

	commit b364828f825
	Author: Daniel Gustafsson <dgustafsson@postgresql.org>
	Date:   Wed Apr 8 22:53:43 2026 +0300
	
	    doc: Fix data_checksums data type
	
	    Commit f19c0eccae96 changed the data_checksums GUC datatype from a
	    boolean to an enum.  This updates the documentation to accurately
	    reflect its new type and document the new possible states: 'on',
	    'off', 'inprogress-on', and 'inprogress-off'.
	
	    Also update the xref for more information to point to the section
	    on data checksums rather than the initdb checksum option.

but it is only a small doc patch, so makes sense to remove him.  I
debated this one at the time I added his name.

  Do not let urgent matters crowd out time for investment in the future.
