Ok, here are the results:
(gdb) p *MyProc

databaseId = 16385, roleId = 16384, lwWaiting = 0 '\0', lwExclusive
= 1 '\001',
lwWaitLink = 0x0, waitLock = 0x0, waitProcLock = 0x0, waitLockMode = 0,
heldLocks = 0, procLocks = {prev = 34618656, next = 34618656}, subxids = {
overflowed = 0 '\0', nxids = 0, xids = {0 <repeats 64 times>}}}
(gdb) p *SerializableSnapshot
$2 = {xmin = 1068152, xmax = 1068155, xcnt = 2, xip = 0x9b142b8, curcid = 0}
(gdb) p *CurrentTransactionState
$3 = {transactionId = 1068154, subTransactionId = 1, name = 0x0,
savepointLevel = 0,
