[GENERAL] 64 and 32 bit libpq
Hello, I am trying to upgrade my postgresql ‘stuff’ to 64 bits from 32 bits. I am running MaxOS Sierra. I have built the 64 bit version of the server and have loaded my database into the new server ( 9.6.2 ). Everything seems to be working. I have some legacy apps that are 32 bit and talk to the server via libpq.dylib. They no longer work with a complaint about not finding a libpq with the right architecture. Can I go back and do a 32 bit rebuild of everything and then take the 32 bit libpq and the 64 bit libpq and use lipo to glue them together and create a ‘fat’ libpq and replace the installed libpq? Is this a safe thing to do? Thanks Jerry -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

Re: [GENERAL] Custom shuffle function stopped working in 9.6

I've seen several sugestions and hints, but seem no one sugested the classical shuffling algorithm. Even when of the solutions seems to be not guaranteed to stop. An easy way to shuffle is swap every element with a random one from its position to the start or end ( NOT a random one on the array, this will give you N^N combinations on an N element array, which does not evenly divide the N! permutations on an array ( see at end ) ) ( of course even my version is not going to give you that given random() is not perfect, but it will be a bit better ). Not having access to a server I've just tried this on 9.3 on sqlfiddlle: CREATE OR REPLACE FUNCTION words_shuffle(in_array varchar[]) RETURNS varchar[] AS $$ declare a varchar[]:=in_array; n integer:=array_length(a,1); tmp varchar; r integer; begin for i in reverse n..2 loop r := floor(random()*i) + 1; tmp=a[i]; a[i]=a[r]; a[r]=tmp; end loop; return a; end $$ LANGUAGE plpgsql volatile As you can see I do it from the end swapping it with elements from the start ( this way I swap i in the range 1..i, instead of i, n wich is a little harder to debug ). I stop at 2 because element 1 can only be swapped with itself. I've marked it volatile as it returns different things each time you call it. My tests show it working, but it may have some problems with the type conversions, as I'm not used to do this kind of code in plpgsql, but you can get the idea. Francisco Olarte.

Re: [GENERAL] Causeless CPU load waves in backend, on windows, 9.5.5 (EDB binary).
Hello all, In order to locate the problem more precisely, I'd like to prepare a test, involving some ping-like communication between the server and a test client. That is, I'd like to repeatedly send something valid to the server and get some valid replies from it, but without any kind of real activity happening on the server. I've looked through the main loop in PostgresMain() but could not find any suitable candidates. Any thoughts? Thank you. Nikolai 03.02.2017 16:30, I wrote: [...] Ok, secure_read() is likely irrelevant too. I think what happened after I inserted "Sleep(15)" into secure_read() is that this "Sleep(15)" was essentially added into the main "for(;;)" loop of PostgresMain (through ReadCommand), introducing an artifical additional CPU relaxation step along with every incoming query and therefore just masking a real CPU eater. So probably I'll have to somehow profile this "for(;;)" in PostgresMain. Thank you.
