>Funny thing is that both PG and Perl are easy enough to build from scratch and the centos compile of Perl at least is
bothancient and horrid enough (5.00503 compatibility, really?) that it's easier to just shell-script both builds and
runit overnight.
>Q: How un-optimized and ancient is the PG on centos?
I agree that it's not all that hard to compile my own Perl and Pg; I've done it in the past. That being said, I'd
preferto avoid it and now I can avoid compiling Pg.
On Centos 6.10, it ships with Perl 5.10.1, which is really ancient to me. Centos 8 ships with 5.14 (IIRC). Still pretty
badand it makes me like your conspiracy theory about Python folks ignoring it on purpose. 😊 They do compile with -O2
andMULTIPLICITY, so it's not too bad.
In the end, I found there were only 2 plperlu functions. Turns out 1 wasn't even used anymore (gotta love legacy code)
andthe other function was only called in 1 place, so it was moved into a module and adjusted (spi_* calls turned into
DBIcalls, etc). After that, there was no more reason for the plperlu extension so the problem no longer matters and I
canload 1 less rpm.
I find it a shame we can't just swap Perl libraries, but I can understand why when I stop to really think about it.
