Ok, here are the results:

(gdb) p *MyProc
$1 = {links = {prev = 4294967295, next = 4294967295}, sem = {semId = 8880136,
semNum = 10}, waitStatus = 0, xid = 0, xmin = 0, pid = 20633,
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,
state = TRANS_ABORT, blockState = TBLOCK_ABORT, nestingLevel = 1,
curTransactionContext = 0x9b06a9c, curTransactionOwner = 0x9ab0294,
childXids = 0x0, currentUser = 0, prevXactReadOnly = 0 '\0', parent = 0x0}
