Hello Murali! I am doing exactly the same at this moment! In our case, the shape files are zip files in the MS SQL database (do these blobs come from MapObjects? then you are probably in the same situation.)
/*The Byte is probably a ZIP, not a shape..*/ What we do: - Extract the blobs with a php-script -> store them as *ZIP* - *Unzip* with the php_zip_lib (or something like that, I am not behind the development machine right now) into a /temp directory/ - start a shell from the php-script that activates ogr2ogr -> ESRI shape to PostGIS for the shape file in the temp directory into a temporary table in PostGIS - Copy the temp table content in PostGIS to a production table with an INSERT statement - loop this sequence Our proces is 80% under control, we are now generating the insert into production (with a little help here on the PostGIS forums, thanks again Kevin) Let me know if you want to know more. ....
