<para> |

<filename>pg.el</filename> is a socket-level interface to |
||||
<productname>Postgres</productname> for emacs (text |
||||
editor extraordinaire). The module is capable of type coercions from a |
||||
range of SQL types to the equivalent Emacs Lisp type. It currently |
||||
supports neither crypt or Kerberos authentication, nor large objects. |

Please note that this is a programmer's API, and doesn't provide any |

form of user interface. Example: |

<programlisting> |

(defun demo () |

(interactive) |
||||
(let* ((conn (pg:connect "template1" "postgres" "postgres")) |
||||
(res (pg:exec conn "SELECT * from scshdemo WHERE a = 42"))) |
||||
(message "status is %s" (pg:result res :status)) |
||||
(message "metadata is %s" (pg:result res :attributes)) |
