Allocate enough shared string memory for stats of auxiliary processes. This fixes a bug whereby the st_appname, st_clienthostname, and st_activity_raw fields for auxiliary processes point beyond the end of their respective shared memory segments. As a result, the application_name of a backend might show up as the client hostname of an auxiliary process.
Backpatch to v10, where this bug was introduced, when the auxiliary processes were added to the array.
