Implement SQL-spec RETURNS TABLE syntax for functions.
...
(Unlike the original submission, this patch treats TABLE output parameters
as being entirely equivalent to OUT parameters -- tgl)

Add a "provariadic" column to pg_proc to eliminate the remarkably expensive
...
need to deconstruct proargmodes for each pg_proc entry inspected by
FuncnameGetCandidates(). Fixes function lookup performance regression
caused by yesterday's variadic-functions patch.
In passing, make pg_proc.probin be NULL, rather than a dummy value '-',
in cases where it is not actually used for the particular type of function.
This should buy back some of the space cost of the extra column.

Support "variadic" functions, which can accept a variable number of arguments
...
so long as all the trailing arguments are of the same (non-array) type.
The function receives them as a single array argument (which is why they
have to all be the same type).
It might be useful to extend this facility to aggregates, but this patch
doesn't do that.
This patch imposes a noticeable slowdown on function lookup --- a follow-on
patch will fix that by adding a redundant column to pg_proc.

Create a type-specific typanalyze routine for tsvector, which collects stats
...
on the most common individual lexemes in place of the mostly-useless default
behavior of counting duplicate tsvectors. Future work: create selectivity
estimation functions that actually do something with these stats.
(Some other things we ought to look at doing: using the Lossy Counting
algorithm in compute_minimal_stats, and using the element-counting idea for
stats on regular arrays.)

Turn PGBE_ACTIVITY_SIZE into a GUC variable, track_activity_query_size.

As the buffer could now be a lot larger than before, and copying it could
thus be a lot more expensive than before, use strcpy instead of memcpy to
copy the query string, as was already suggested in comments. Also, only copy
the PgBackendStatus struct and string if the slot is in use.
