Postgresql streaming replication forward writes -

-

i've managed set streaming replication postgresql (9.3 if maters). however, applications access secondary server (of course) unable make insert statements.

is there way have secondary server forward writes primary?

there no built-in support @ time (9.5 or older, @ least) transparently redirecting sessions read-replica writeable master. nor aware of attempting develop such support.

it's more complicated might expect redirection of write changes master read-replicas in way preserves acid transaction semantics (proper isolation, locking, etc) properly, apps don't have "know" , take special care.

the pgpool-ii project has (limited) support doing via proxy layer, , best bet @ point. aware there significant limitations , potential transaction consistency violations created proxy-based read/write split.

there couple of multi-master solutions, really shouldn't go there unless know need it. i'm active developer on one of them i'm aware of compromises , issues multi-master brings. don't go there unless really, have to.

mysql - FireDac error 314 - but DLLs are in program directory -

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.

-
so per documentation https://developer.github.com/v3/repos/releases/#list-releases-for-a-repository get /repos/:owner/:repo/releases should list relases , https://api.github.com/repos/jquery/jquery/releases should list releases in jquery project , not , why ? because repository doesn't have releases. has tags github presenting in releases page. for more clear example, see: https://github.com/hashicorp/terraform/releases which has both releases , tags showing on page, api shows releases: https://api.github.com/repos/hashicorp/terraform/releases
