I'm after experiences similar to what you are describing with lo_export. I have used lo_import and ol_export to test image storage and retrival. One problem that you mention is with super user access required to export to the local file system. The second problem is that it seems to add another layer to a web application. A table constructed that contains pointers outside the database seems to be the easiest to deal with in terms of retrieval of images and dislpay within a web page.
Anyone that that is using Postgres for storage and retrival of images please post your experiences. Thank you. >-----Original Message----- >From: Andrei Bintintan [mailto:[EMAIL PROTECTED] >Sent: Wednesday, November 26, 2003 02:20 PM >To: 'Daniel Rubio', [EMAIL PROTECTED] >Subject: Re: [ADMIN] pg_lo_import alternative ... > >Are there many images? > >I do not suggest to store the images in the database.
