Tom Lane 5d0800000e Correctly copy the target host identification in PQcancelCreate.
PQcancelCreate failed to copy struct pg_conn_host's "type" field,
instead leaving it zero (a/k/a CHT_HOST_NAME).  This seemingly
has no great ill effects if it should have been CHT_UNIX_SOCKET
instead, but if it should have been CHT_HOST_ADDRESS then a
null-pointer dereference will occur when the cancelConn is used.
