.IX Header "DESCRIPTION"
This class implements autoincrements for PostgreSQL.
.SH "POSTGRESQL SCHEMA SUPPORT"
.IX Header "POSTGRESQL SCHEMA SUPPORT"
This driver supports multiple PostgreSQL schemas, with one caveat: for
performance reasons, data about the search path, sequence names, and
so forth is queried as needed and \s-1CACHED\s0 for subsequent uses.
.PP
For this reason, once your schema is instantiated, you should not
change the PostgreSQL schema search path for that schema's database
connection. If you do, Bad Things may happen.
.PP
You should do any necessary manipulation of the search path \s-1BEFORE\s0
instantiating your schema object, or as part of the on_connect_do
option to \fBconnect()\fR, for example:
.PP
.Vb 6
\&   my $schema = My::Schema\->connect
\&                  ( $dsn,$user,$pass,
\&                    { on_connect_do =>
\&                        [ \*(AqSET search_path TO myschema, foo, public\*(Aq ],
\&                    },
