[GENERAL] tracking postgres

1999-04-20 Thread Guo Ge 

hi all
I am tracking  the psql and postgres recently.After psql sends the
query to the backend,I cann't continue to track.I don't know  how the
postgres puts the results into the conn. Because the psql gets results
of query afetr it sends query.
If I   do "gdb postgres" , because of the variable dset=debug, I
cann't find the process of setting PGResult where dest=Local or Remote.
who can tell me the way to solve the bored problem?
Thanks.

hello ,all:
   It's known that some database system such as Oracle,Sysbase can
support the Two-Phase Commit that postgreSQL cann't. I want to  make the
postgreSQL cooperate with other database under a transaction manager so
that we can deal  with distributed  transactions.
   Now I met some questions.I wish someone can help me.
   First, I have  some trouble with log. I cann't find out the log's
structure. I find the system writes two bits into block when a
transaction commits.Maybe they the log's records.Is it right?
  Second ,I want to know the position of source codes about the postgres
dealing with the input from the frontend such as psql.
 I'm eager to your helps.Thanks.
 If you are interested in the transaction processing,please send mail to
me([EMAIL PROTECTED]).
