Re: pgsql: Fix pattern matching logic for logs in TAP tests of pgbench

Hello Andrew & Michaël,

Yep. The idea was that other tests would go on being collected eg if the 
file is not found, but it should have been checked anyway.

Indeed.

However, if slurp_file fails it raises an exception and aborts the whole 
TAP unexpectedly, which is pretty unclean. So I'd suggest to keep the 
eval, as attached. I tested it by changing the file name so that the slurp 
fails.

Probably: My very old perl expertise is fading away because I'm not using 
it much these days. Cannot say I miss it:-)
