Re: jpg error 53
Hi, PostgreSQL 9.0 introduced bytea_output=hex (as default also), prior to that version only bytea_output=escape was supported. If you using libpq.dll from postgres 8.4 it will support only byte_output=escape. Either change your libpq.dll version, or change bytea_output to escape, so it will be prop...

Re: TZPgEventAlerter
Hi, this component does work:) but you must remember that only one of this components can actually receive notifications from database (that's pg_notify design). So try with only one PgEventAlerter in your app, aor if you use more of them - assign Processor component to them so you will always have ...

Michael, Thanks for the information - this means my old apps will work without much work:) For new ones i'll make sure to create queries that will fit for CAPI statement convention. I expected that handle_indeterminate_datatype option is quick patch for testing purposes, and sooner or later it would...

Michael, Thank You for this patch. I've tired it on my app: Adding 'handle_indeterminate_datatype=true' to TZConnection doesn't seem to do anything - i still got error about unknown param types. But adding it to TZQuery does the trick - i've used ZEOS with Postgresql CAPI and no errors about unknown...
