pgExpress Driver Params Demo
Vita Voom Software
-----------------------------------------------------------------------
This is a simple demo that will search using Params to look for 
specific values in the PostgreSQL pg_type table.

Notes:
1) For Kylix/Delphi portibility reasons, this demo Uses the CLX, not 
   VCL. It might look "flickering" for VCL users. The code is similar, 
   however.
2) Kylix and Delphi 6 do not have the TSimpleDataset component. Delphi 
   7 has TSQLClientDataset but it's on a Demos dir and not installed 
   by default (Borland has discontinuated it's use). The most portable
   way to do this demo is the one presented: using a client dataset, a 
   SQL dataset  and a DatasetProvider.
3) Do not edit the pg_type table presented by default. It is a system 
   table and you could be damaging your database system.
4) The '~~' operator found in the sdsParams query is a PostgreSQL 
   operator similar to the LIKE keyword. The '%' char in the default
   search string is a ""match zero or any number of chars" char (like 
   '*' on the files mask i.e. '*.*' or '*.exe''.
