Which brings me back to PostgreSQL - which was commented as not having a

one SQLite is using. People who target PostgreSQL will already have had

You really need to specify _who_ you want to protect the database from;
what kind of access, etc.
I think the answer you're looking for is the SQLite "client" provides
access control to SQLite- not the other way around- that is, you must
control all clients allowed access to the database in order

Usually they don't.
If your program actually depends on SQLite the dynamic linker will bring
the greatest non-api-incompatible version in automatically. You simply
add -lsqlite to the link list and libsqlite.so will automatically be
brought in- thus saving disk space at the expense of startup time
You need to register a new function with-state to do this. Something
like this:
void f(sqlite_func *ctx, int arg, const char **argv)
{
int *state = (int *)sqlite_user_data(ctx);
if (atoi(argv[0]) == atoi(argv[1])) *state = 1;
sqlite_set_result_int(ctx, *state);
}

Instead of keeping an "undo" journal- consider using a "changes"
journal-- each writer could use it's own journal then only at commit
would each worker actually start making changes to the database.

Actually, I knew... I don't think this is a bug, but instead a feature.
Note it has nothing at all to do with closing the file descriptor. In my

The hard part is to do it portably.
I use a multicast socket that writes the change-event. Then I use a
select() call on the multicast socket in other clients- if they see the
change event, they incorporate the new data into their cache.
If you want it reasonably seamless, create triggers that ev
You can create a new function to do this quite painlessly. Poke around
the wiki for information on creating a new function, or read the source.
But beware: consider creating one that uses SHA1 or MD5 as a hashing
function instead of your local systems' crypt() as not all crypt() are
created equal.

You really should point out if you're familiar with other environments,
and ask questions that represent your eventual goals.
You're fishing right now, and your questions are so loaded it's not even

Whenever you think you need to "add a field" - add a whole new table and
use joins anywhere you need access to the new field.
