=head1 NAME
Alzabo::PostgreSQL - Alzabo and PostgreSQL
=head1 DESCRIPTION
This documentation is about what special support Alzabo has for PostgreSQL,
as well as what is lacking.
Postgres support is based on the 7.3.x version of Postgres. Alzabo
should work with the 7.1 and 7.2 series, and may even work with the
7.0 series.
=head2 Mixed-case Table or Column Names
By default, Postgres treats table and column names case-insensitively.
Because of this, Alzabo always quotes these names when generating DDL
SQL. If you are using tables or columns that contain upper-case
characters, you should always call C<<
$schema->set_quote_identifiers(1) >> as soon as you load your schema
object. Otherwise, any method which generates DML SQL will fail.
=head2 Reverse Engineering
=over 4
=item *
Alzabo cannot determine from the existence of a sequence that the
sequence is meant to be used for a particular column unless the
sequence was created as a result of making a column's type SERIAL.
This is because there is no link between the two in the Postgres' data
dictionary tables and will probably never change.
=back
=head2 Transactions
=over 4
=item *
Transactions are fully supported with Postgres.
=back
=head2 Outer joins
=over 4
=item *
Left and right outer joins are supported.
=item *
Full outer joins are not supported.
=back
=head2 Constraints
Column constraints can be specified as column attributes. Table
constraints can be specified as table attributes.
Foreign key constraints are generated automatically based on the
relationships defined by your schema.
