I'm a newbie to database admin, but I'm not afraid to try - but this one has me stumped. I'm using SQL-Ledger as a front end to postgresql 7.4.2. on (mostly) Debian Testing, i386. My fiscal year is over and I would _like_ to prevent any changes to the data from last year. I looked/searched in the manual, but I don't even know what to call what it is that I'm trying to do! "lock" has another meaning for databases. :) "Write" seems to bring up lots of user-related stuff. So, I'm hoping one of you geniuses can tell me where to look, what to look for, or how to do it. *smile* Thanks!
