[Postgres-xc-developers] patch for gtm program exit when fail to create thread

[Wang D. <dia...@qq...>]

Hi,

this patch reduce error level to LOG in ServerLoop() for GTM and GTM proxy.
    
Because PG_exception_stack not set in main thread, elog with
ERROR(eg. thread create failed) can cause whole program exit, see
pg_re_throw(). This patch refers to error process of postmaster,
which just log error.

Note, palloc still used in ServerLoop(), which will raise a ERROR
message if out of memory, fix it need another patch.
