I would like each database to encapsulate its own backup procedure.
Each database contains a table (fsyslog) which has a record of each
backup taken:
<rowid><Operator><timestamp><destination path>
At the application level I presently
a) check for time since the last backup
b) if older than <x> hrs
(i) perform a vacuum analyze
(ii) force a call to dbbackup
(iii) add a new record into fsyslog
I would like to add a procedure to the database that does the backup and
thus ensure that all applications use the same methodology.
The procedure would take only the backup path as a parameter.
presently I send the command :
pch := pchar('pg_dump -C -h '+host+' -U '+usr+' -p '+pswd+ ' -f
'+bckup_path+' '+dbase);
to postgres.
as the operator is obviously logged in how do I
(1) trap their user id
(2) Send the call to pg_dump without knowing their password?
I expect this is a well worn route and am hoping not to have to reinvent
a wheel.
thanks very much as always
Richard
