Specific for updating 7.4.1->7.4.x:
|
|
|
|
A dump/restore is *not* required for those running 7.4, BUT:
|
|
|
|
If you want to install the fixes in the information schema you will
|
|
need to reload it into the database. This is either accomplished by
|
|
initializing a new cluster by running "initdb", or by running the
|
|
following sequence of SQL commands in each database (ideally including
|
|
template1) as a superuser in psql, after installing the new release:
|
|
|
|
DROP SCHEMA information_schema CASCADE;
|
|
\i /usr/local/pgsql/share/information_schema.sql
|
|
|
|
Fixes to the information schema (from HISTORY):
|
|
* Fix information schema for bit data types (Peter)
|
|
* Fix information schema view constraint_column_usage for foreign
|
|
keys (Peter)

For procedural languages and postgresql functions, please note that
|
|
you might have to update them when updating the server. For example,
|
|
the "elog" method disappeared in postgresql-7.4, so postgresql-contrib
|
|
must be updated along with the server.
|
|
|
|
If you have many tables and many clients running, consider raising
|
|
kern.maxfiles using sysctl(8), or reconfigure your kernel
|
|
appropriately.
|
|
|
|
You should vacuum and backup your database regularly. There is a
|
|
periodic script, /usr/local/etc/periodic/daily/502.pgsql, that you may
|
|
find useful. See the script for instructions.
|
|
|
|
To allow many simultaneous connections to your PostgreSQL server, you
|
|
should raise the SystemV shared memory limits in your kernel. Here are
|
|
example values for allowing up to 180 clients (configurations in
|
|
postgresql.conf also needed, of course):
|
|
options SYSVSHM
|
|
options SYSVSEM
|
|
options SYSVMSG
|
|
options SHMMAXPGS=65536
|
|
options SEMMNI=40
|
|
options SEMMNS=240
|
|
options SEMUME=40
|
|
options SEMMNU=120
|
|
|
|
If you plan to access your PostgreSQL server using ODBC, please
|
|
consider running the SQL script /usr/local/share/postgresql/odbc.sql
|
|
to get the functions required for ODBC compliance.
|
|
|
|
======================================================================
|
|
|
|
To initialize the database, run
|
|
|
|
/usr/local/etc/rc.d/010.pgsql.sh initdb
|
|
|
|
You can then start PostgreSQL by running:
|
|
|
|
/usr/local/etc/rc.d/010.pgsql.sh start
|
|
|
|
For postmaster settings, see ~pgsql/data/postgresql.conf
|
|
|
|
NB. FreeBSD's PostgreSQL port now by default logs to syslog
|
|
See ~pgsql/data/postgresql.conf for more info
|
|
|
|
======================================================================
|
|
|
|
To run PostgreSQL at startup, add
|
|
'postgresql_enable="YES"' to /etc/rc.conf
|
