pg_restore: [custom archiver] could not read from input file: end of file

I’ve been a fan of PostgreSQL since 2000 when I switched to it from MySQL. I wanted stored procedures and functions. I got that with PostgreSQL. I was used to having such features from my years working with other big databases such as DB2, Oracle, and Sybase. I’ve been moving towards using the custom format …

Using compression with PostgreSQL’s pg_dump

I attended a few of the talks at PGCon 2013 last month. One talk, for which I took several notes and made a few choice tweets. The main one I’m following up on is using the -Fc option on pg_dump. It was during Magnus Haganders’ talk on PostgreSQL Backup Strategies that I posted that tweet. …

After a short bit of struggle, I had just one service check that was failing: check_ping. Here’s the example: $ /usr/local/libexec/nagios/check_ping -H bast.example.org -w …
