Hello All
Here is the presentation, it was done under "Percona University Athens".
It went ok, I think, although people didn't seem to understand much, as
the audience was MySQL/PostgreSQL/Mongo/Oracle mix. However some young
people seemed to be interested as they asked questions afterwards.

Dear all,
I’m reasonably experienced with Postgres with simple (single, „rebuild
and restore“) requirements, but would need some hints on what to look
for in a more complex situation - deploying Postgres as the backend for
a (virtual) appliance.

It looks to me like fmgr_sql does take a new snapsho

hi.
table "test" does not exist.
---1.this will work.
CREATE or replace PROCEDURE template_create() LANGUAGE SQL
AS $proc$ DROP TABLE if exists test cascade; CREATE TABLE test(id
int4range,valid_at tsrange,name text);$proc$;
2.this will have errors.
CREATE or replace PROCEDURE template_create
