> Updated patch attached. I think we need to improve postgresql.conf.sample a bit more, especially the long line for #log_csv_fields = '...'. 330 characters in it! #1. Leave the long line because it is needed. #2. Hide the variable from the default conf. #3. Use short %x mnemonic both in log_line_prefix and log_csv_fields. (It might require many additional mnemonics.) Which is better, or another idea?

This was > specifically addressed in the thread leading up to this patch... I think it depends default log filename, that contains %S (seconds) suffix. We can remove %S from log_filename; if we use a log per-day, those log might contain different columns even after restart. If we cannot avoid zigged csv fields completely, SIGHUP seems reasonable for it. >> * What objects do you want to allocate in TopMemoryContext in >> assign_log_csv_fields() ? > I just moved the switch to Top to be after those are allocated. How about changing the type of csv_log_fields from List* to fixed array of LogCSVFields? If so, we can use an array-initializer instead of build_default_csvlog_list() ? The code will be simplified. Fixed length won't be a problem because it would be rare that the same field are specified many times. >> * Docs need some tags for itemized elements or pre-formatted codes. >> They looks itemized in the sgml files, but will be flattened in >> complied HTML files. > > Not sure what you're referring to here...?
