Assume I have a bank app.. When customer withdraws $10 from his accouint I
have to do following
--> update account_summary table [subtract $10 from his account]
--> update account detail_table [with other transaction details]
Requirement:
either both transactions should succeed or both transactions should
be rolled back in case of failure.
Question:
if my first update succeeds and second fails (say due to space
errors .. I have inconsistancy ..
Per the thread below stored procedures/functions cannot have commits. I
assume that means that they will be implicitly commited ??
How do I approach this simple requirment using psql ?
Thx
Deep

Do you know if it will be solved sometime? Or this is architecture
dependend problem? I mean that transactions are rulez and very helpful
rulez when working with large databases.
Nested transactions are on the todo list, but I don't know when they will
appear.
