I am wondering if there is a way to prevent a cell's text from overlapping into the adjacent cell(s) without having to resize the cell itself, or set the cell contents to wrap.


Question: InstallHandler runs under a special ghost user. What rights does it have?
Answer: After trial and error investigation, it appears the InstallHandler can run with unlimited privileges given one special condition; the InstallHandler implementor must have without sharing annotation.

Running without sharing allows the install user context to:


view all data
modify all data
interrogate system data (like CronTrigger and ApexClass)


The install user context cascades into any Batch Apex and Scheduled Apex jobs that are invoked as part of the post install script. If those classes are also annotated without sharing, it offers the capability of long-running "super user" processes.
