# SQL::Translator::Parser::PostgreSQL(3pm)

parser for PostgreSQL

## NAME

SQL::Translator::Parser::PostgreSQL - parser for PostgreSQL

## SYNOPSIS

```
  use SQL::Translator;
  use SQL::Translator::Parser::PostgreSQL;
  my $translator = SQL::Translator->new;
  $translator->parser("SQL::Translator::Parser::PostgreSQL");
```

## DESCRIPTION

The grammar was started from the MySQL parsers.  Here is the description from PostgreSQL, truncated to what's currently supported (patches welcome, of course) :

Table: (http://www.postgresql.org/docs/current/sql-createtable.html)

```
  CREATE [ [ LOCAL ] { TEMPORARY | TEMP } ] TABLE table_name (
      { column_name data_type [ DEFAULT default_expr ]
         [ column_constraint [, ... ] ]
      | table_constraint }  [, ... ]
  )
  [ INHERITS ( parent_table [, ... ] ) ]
  [ WITH OIDS | WITHOUT OIDS ]
  where column_constraint is:
  [ CONSTRAINT constraint_name ]
  { NOT NULL | NULL | UNIQUE | PRIMARY KEY |
    CHECK (expression) |
    REFERENCES reftable [ ( refcolumn ) ] [ MATCH FULL | MATCH PARTIAL ]
      [ ON DELETE action ] [ ON UPDATE action ] }
  [ DEFERRABLE | NOT DEFERRABLE ] [ INITIALLY DEFERRED | INITIALLY IMMEDIATE ]
  and table_constraint is:
  [ CONSTRAINT constraint_name ]
  { UNIQUE ( column_name [, ... ] ) |
    PRIMARY KEY ( column_name [, ... ] ) |
    CHECK ( expression ) |
    EXCLUDE [USING acc_method] (expression) [INCLUDE (column [, ...])] [WHERE (predicate)]
    FOREIGN KEY ( column_name [, ... ] )
     REFERENCES reftable [ ( refcolumn [, ... ] ) ]
      [ MATCH FULL | MATCH PARTIAL ] [ ON DELETE action ] [ ON UPDATE action ] }
  [ DEFERRABLE | NOT DEFERRABLE ] [ INITIALLY DEFERRED | INITIALLY IMMEDIATE ]
```

Index : (http://www.postgresql.org/docs/current/sql-createindex.html)

```
  CREATE [ UNIQUE ] INDEX index_name ON table
      [ USING acc_method ] ( column [ ops_name ] [, ...] )
      [ INCLUDE  ( column [, ...] ) ]
      [ WHERE predicate ]
  CREATE [ UNIQUE ] INDEX index_name ON table
      [ USING acc_method ] ( func_name( column [, ... ]) [ ops_name ] )
      [ WHERE predicate ]
```

Alter table:

```
  ALTER TABLE [ ONLY ] table [ * ]
      ADD [ COLUMN ] column type [ column_constraint [ ... ] ]
  ALTER TABLE [ ONLY ] table [ * ]
      ALTER [ COLUMN ] column { SET DEFAULT value | DROP DEFAULT }
  ALTER TABLE [ ONLY ] table [ * ]
      ALTER [ COLUMN ] column SET STATISTICS integer
  ALTER TABLE [ ONLY ] table [ * ]
      RENAME [ COLUMN ] column TO newcolumn
  ALTER TABLE table
      RENAME TO new_table
  ALTER TABLE table
      ADD table_constraint_definition
  ALTER TABLE [ ONLY ] table
          DROP CONSTRAINT constraint { RESTRICT | CASCADE }
  ALTER TABLE table
          OWNER TO new_owner
```

View :

```
    CREATE [ OR REPLACE ] VIEW view [ ( column name list ) ] AS SELECT query
```
