Hi,
is there any way to set Auto-Rollback : ON, automaticly during
instalation process or using query (maybe something like set autocommit
= 'on')?
We need it to automaticly close the transaction if an error occures
during implementing patches.
How are you applying the patches?
With what library/interface/etc?
For instance in psql you have:
https://www.postgresql.org/docs/9.6/static/app-psql.html
"AUTOCOMMIT
When on (the default), each SQL command is automatically committed
upon successful completion. To postpone commit in this mode, you must
enter a BEGIN or START TRANSACTION SQL command. When off or unset, SQL
commands are not committed until you explicitly issue COMMIT or END. The
autocommit-off mode works by issuing an implicit BEGIN for you, just
before any command that is not already in a transaction block and is not
itself a BEGIN or other transaction-control command, nor a command that
cannot be executed inside a transaction block (such as VACUUM).
Note: In autocommit-off mode, you must explicitly abandon any
failed transaction by entering ABORT or ROLLBACK. Also keep in mind that
if you exit the session without committing, your work will be lost.
Note: The autocommit-on mode is PostgreSQL's traditional
behavior, but autocommit-off is closer to the SQL spec. If you prefer
autocommit-off, you might wish to set it in the system-wide psqlrc file
or your ~/.psqlrc file.
"
NOTE that you have to explicitly ROLLBACK a failed transaction though.
Thanks in advanced for the answear.
