I keep getting
Uncaught exception: Could not open extension /etc/hhvm/extensions/pgsql.so: /etc/hhvm/extensions/pgsql.so: undefined symbol: _ZN4HPHP13PDOConnection5sweepEv
When I try to start up HHVM. It was working prior to a HHVM which I applied (yesterday) as part of the standard upgrade process.
Rebuilding the pgsql.so fails with the bulk of the problem seeming to rest in the file
hhvm-pgsql-master/pdo_pgsql_statement.cpp
Is there a patch for this, or how would I be able to revert to a version of HHVM that does support this postgres extension?
