Fixed counting bug in parsing "->" operator.
Removed that silly debugging function I accidently committed last night.

Document why certain GUC variables aren't in postgresql.conf.

Add support for PGHOST, PGPORT, PGUSER environment variables

repeating my mistake.

protocol 3, then falls back to 2 if postmaster rejects the startup packet
with an old-format error message.  A side benefit of the rewrite is that
SSL-encrypted connections can now be made without blocking.  (I think,
anyway, but do not have a good way to test.)

catalog lookups when not in a transaction.  This prevents bizarre
failures if someone tries to set a value for session_authorization in
postgresql.conf.  Per report from Fernando Nasser.

extensions to support our historical behavior.  An aggregate belongs
to the closest query level of any of the variables in its argument,
or the current query level if there are no variables (e.g., COUNT(*)).
The implementation involves adding an agglevelsup field to Aggref,
and treating outer aggregates like outer variables at planning time.

Per recent gripe.

#define PG_ENCODING_BE_LAST PG_ISO_8859_8
#define PG_ENCODING_FE_LAST PG_WIN1256

but the last client encoding in the enum list is actually PG_GB18030 and
it seems that

#define PG_ENCODING_IS_CLIEN_ONLY(_enc) \
                (((_enc) > PG_ENCODING_BE_LAST && (_enc) <= PG_ENCODING_FE_LAST)

can never be true.

I think the define should read
#define PG_ENCODING_FE_LAST PG_GB18030

On the other hand, perhaps no-one cares, because
PG_ENCODING_IS_CLIEN_ONLY is never used.
