   http://home.cogeco.ca/~ve3wwg/apq-1.93.tar.gz

is the 1.93 sources (PostgreSQL only). The PDF manual
has examples for almost every API function, and is
found at:

   http://home.cogeco.ca/~ve3wwg/apq_manual.pdf

The version 2.0 is not quite ready yet, but it is
the one that will support the common functions
between PostgreSQL and MySQL. There are a few
challenges in doing this, and so even version
2.0 will not yet include MySQL blob support for
example (it has full support for PostgreSQL
however). All other normal RDBMs functions will
be available, however.

APQ version 2.0 is pending more testing, and
updates to the "manual". If you have an urgent need to
try an alpha release, contact me privately
(at v e 3 w w g @ c o g e c o . c a)
and we can arrange something.

Here is the little vers 1.93 sales blurb from the
web page:

   The following are reasons you want to use APQ as
   your Ada95 binding to the PostgreSQL database:

  - It is a thick binding to the PostgreSQL database
    library libpq
  - Very simple to use
  - Uses Ada95 data types only (no C language interfaces)
  - Full BLOB support (PostgreSQL)
     - Open/Create blobs
     - Read/Write blobs using Ada95 stream I/O
     - Buffered BLOB I/O for greater performance
  - Generic functions and procedures allowing strongly
    typed programming
  - Very simple to install under Linux/FreeBSD:
  - Simple compile and install process
  - Only depends upon PostgreSQL libpq
  - No ODBC required!  Direct interface to database.
  - No GNADE infrastructure required (simple install).
  - Full support of NULL indicators (strongly typed)
  - Source code is almost all Ada95 (tested under GNAT-3.13p, FreeBSD)
  - 120+ page programmer's manual (almost all functions
    have an example code fragment)
  - ACL or GPL2 license (dual license - you choose)
  - win32 clients can be supported
  - Under active development

Here is a testamonial :

  "Thanks for 'apq'. The packages are easy to understand and use,
  and the doc's are helpful. With the help of 'apq' and 'PostgreSQL',
  I was able to build a largish, functional database in less
  than a week."
