Hello Tom & Michaël,
I think this patch should be rejected.
+1 for rejection [...]
The noes have it!
Note that the motivation was really symmetric completion:
fabien=# \echo :VERSION_NAME
11devel
fabien=# \echo :VERSION_NUM
110000
fabien=# \echo :VERSION
PostgreSQL 11devel on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu
5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609, 64-bit
fabien=# \echo :SERVER_VERSION_NAME
10.1
fabien=# \echo :SERVER_VERSION_NUM
100001
But
fabien=# \echo :SERVER_VERSION
:SERVER_VERSION
To get it into a variable the work around is really:
fabien=# SELECT version() AS "SERVER_VERSION" \gset
fabien=# \echo :SERVER_VERSION
PostgreSQL 10.1 on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu
5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609, 64-bit
