Libraries commonly use shared memory to store hash tables. While it's
possible to set up a dshash table using the DSM registry today, doing so is
complicated; you need to set up two LWLock tranches, a DSA, and finally the
dshash table. The attached patch adds a new function called
GetNamedDSMHash() that makes creating/attaching a hash table in the DSM
registry much easier.
