First of all, 3 to 6 months isn't that long of an uptime, as I've seen systems with 2+ years. And with the distributions you've listed there won't be any major kernel updates in that time, save important security updates, and even those don't force a reboot (but the new kernel will only be used after a reboot). If you really need high availability, better to look into proper redundancy by setting up a cluster, where a second node can easily take over should the primary suffer a hardware defect.
Unfortunately I'm not a cluster guy Smilie. On my home server I use CentOS but i see that there is a kernel update each month. Should I reboot each time? Where could I find information about each update. Is it a security or a normal and I can postpone reboot.

PG_LAST_NOTICE(3)														 PG_LAST_NOTICE(3)

pg_last_notice - Returns the last notice message from PostgreSQL server

SYNOPSIS
string pg_last_notice (resource $connection) DESCRIPTION
pg_last_notice(3) returns the last notice message from the PostgreSQL server on the specified $connection. The PostgreSQL server sends notice messages in several cases, for instance when creating a SERIAL column in a table. With pg_last_notice(3), you can avoid issuing useless queries by checking whether or not the notice is related to your transaction. Notice message tracking can be set to optional by setting 1 for pgsql.ignore_notice in php.ini. Notice message logging can be set to optional by setting 0 for pgsql.log_notice in php.ini. Unless pgsql.ignore_notice is set to 0, notice message cannot be logged. PARAMETERS
o $connection - PostgreSQL database connection resource. RETURN VALUES
A string containing the last notice on the given $connection, or FALSE on error. CHANGELOG
+--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 4.3.0 | | | | | | | This function is now fully implemented. Earlier | | | versions ignores database connection parameter. | | | | | 4.3.0 | | | | | | | The pgsql.ignore_notice and pgsql.log_notice | | | php.ini directives were added. | | | | | 4.0.6 | | | | | | | PHP 4.0.6 has problem with notice message han- | | | dling. Use of the PostgreSQL module with PHP | | | 4.0.6 is not recommended even if you are not | | | using pg_last_notice(3). | | | | +--------+---------------------------------------------------+ EXAMPLES
Example #1 pg_last_notice(3) example <?php $pgsql_conn = pg_connect("dbname=mark host=localhost"); $res = pg_query("CREATE TABLE test (id SERIAL)"); $notice = pg_last_notice($pgsql_conn); echo $notice; ?> The above example will output: CREATE TABLE will create implicit sequence "test_id_seq" for "serial" column "test.id" SEE ALSO
