"Would it be necessary to modify the wire protocol to support multiple query/result-set combinations per server round-trip? That is, to be able to send a hundred different queries (each with a different number and type of columns in the result set) and receive a hundred different results all in a single network round-trip? That is …
The wire protocol is the language spoken between a client and the server of postgresql. The majority of programming languages out there do not implement their own version of the protocol instead opting to bind to the C library libpq. There …
So what is the problem? The problem is they weren't running Autovacuum. Now many …
Yes, I really did just write that. I believe the the FSF no longer fulfills its mission. Wait, let's back up a step. I can feel the torches started to be covered in pitch and the frankenstein cry of, "kill the heretic" starting to rumble through the old streets of the Free Software country. I am not here to say that the FSF is …
Bucardo, an asynchronous multi-master replication system (or, maybe the asynchronous multi-master replication system for PostgreSQL, cause I know of no other actively developed ones), deals with replication conflicts by providing conflict handlers in a form of standard (built-in) or custom code procedures. The built-in conflict handlers resolve a conflict by taking a row from the source or the target databases (in Bucardo 4 only 2 masters are supported, called 'source' …
This has been cooking for a while now, and now it's time to open it up: July 31st, 2012 was my last day with Command Prompt, Inc.
I joined Command Prompt in October 2005. Back then I wasn't a very prolific blogger, it seems, because it took me six months to get this fact out. I haven't improved much since then, even though boss Josh Drake kept telling me …
I don't usually post rants here, but this one might be actually helpful to others, so let's make an exception. It will be related to installing PostgreSQL from distro-specific packages. I usually prefer setting PostgreSQL from sources, unlike the majority of users; nevertheless, I'm familiar with how popular distros, like Debian or Fedora, manage their PostgreSQL layouts. Or so I thought until today.
My task was simple: install PostgreSQL instance …
WAL (acronym for the Write Ahead Log) is the mechanism that Postgres uses to implement durability (the D in ACID) of data changes in the face of a system crash. WAL is also a critical component for Postgres to provide binary replication as well as online binary backups.
