I use this script for changing icons. Maybe it can help you in looking for the solution. Simply look for correct table.
oldicon = 'oldicon.svg'
newicon = 'newicon.svg'
db:query('UPDATE visobjects SET params=replace(params,?,?)', oldicon, newicon)
oldicon = 'oldicon.svg'
newicon = 'newicon.svg'
db:query('UPDATE visobjects SET params=replace(params,?,?)', oldicon, newicon)
