.BR "Create Table"
@@ -70,52 +67,12 @@ must satisfy for an insert or update operation to succeed. Each constraint
must evaluate to a boolean expression. Multiple attributes may be referenced within
a single constraint.
.PP
-The optional
-.BR store
-and
-.BR arch_store
-keywords may be used to specify a storage manager to use for the new
-class. The released version of Postgres supports only \*(lqmagnetic
-disk\*(rq as a storage manager name; the research system at UC Berkeley
-provides additional storage managers.
-.BR Store
-controls the location of current data,
-and
-.BR arch_store
-controls the location of historical data.
-.BR Arch_store
-may only be specified if
-.BR archive
-is also specified. If either
-.BR store
-or
-.BR arch_store
-is not declared, it defaults to \*(lqmagnetic disk\*(rq.
-.PP
The new class is created as a heap with no initial data. A class can
have no more than 1600 attributes (realistically, this is limited by the
fact that tuple sizes must be less than 8192 bytes), but this limit
may be configured lower at some sites. A class cannot have the same
name as a system catalog class.
.PP
-The
-.BR archive
-keyword specifies whether historical data is to be saved or discarded.
-.IR Arch_mode
-may be one of:
-.TP 10n
-.IR none
-No historical access is supported.
-.TP 10n
-.IR light
-Historical access is allowed and optimized for light update activity.
-.TP 10n
-.IR heavy
-Historical access is allowed and optimized for heavy update activity.
-.PP
-.IR Arch_mode
-defaults to \*(lqnone\*(rq. Once the archive status is set, there is
-no way to change it. For details of the optimization, see [STON87].

-.TH PURGE SQL 11/05/95 PostgreSQL PostgreSQL
-.SH NAME
-purge \(em discard historical data
-.SH SYNOPSIS
-.nf
-\fBpurge\fR classname [ \fBbefore\fR abstime ] [ \fBafter\fR reltime ]
-.fi
-.SH DESCRIPTION
-.BR Purge
-allows a user to specify the historical retention properties of a
-class. If the date specified is an absolute time such as \*(lqJan 1
-1987\*(rq, Postgres will discard tuples whose validity expired before
-the indicated time.
-.BR Purge
-with no
-.IR before
-clause is equivalent to \*(lqpurge before now\*(rq. Until specified
-with a purge command, instance preservation defaults to
-\*(lqforever\*(rq.
-.PP
-The user may purge a class at any time as long as the purge date never
-decreases. Postgres will enforce this restriction, silently.
-.PP
-Note that the
-.BR purge
-command does not do anything except set a parameter for system
-operation. Use
-.IR vacuum (l)
-to enforce this parameter.
-.SH EXAMPLE
-.nf
---
---Always discard data in the EMP class
---prior to January 1, 1989
---
-purge EMP before "Jan 1 1989"
-.fi
-.nf
---
---Retain only the current data in EMP
---
-purge EMP

-vacuum(l).
-.SH "BUGS AND CAVEATS"
-Error messages are quite unhelpful. A complaint about
-\*(lqinconsistent times\*(rq followed by several nine-digit numbers
-indicates an attempt to \*(lqback up\*(rq a purge date on a relation.
-.PP
-You cannot purge certain system catalogs (namely, \*(lqpg_class\*(rq,
-\*(lqpg_attribute\*(rq, \*(lqpg_am\*(rq, and \*(lqpg_amop\*(rq) due
-to circularities in the system catalog code.
-.PP
-This definition of the
-.BR purge
-command is really only useful for non-archived relations, since
-tuples will not be discarded from archive relations (they are
-never vacuumed).

If the server crashes during a vacuum command, chances are it will leave
a lock file hanging around. Attempts to re-run the vacuum command
result in an error message about the creation of a lock file. If you
