1. C++ style comments in C source for ecpg ( // comment )
2. compiler finds wrong include file extern.h in ecpg/lib/descriptor.c
from
include path instead of workdir (rename it ?)
3. fe-connect getsockopt takes a socklen_t as fifth arg not int (use
SOCKET_SIZE_TYPE instead)
4. char vs unsigned char in psql calls to libpq
5. empty define that results in an empty but terminated line ( ; )
Now for all but point 3 I can supply changes to the
compiler flags, to make the compiler less pedantic.
Or is someone interested in the complications ?
in the meantime can someone apply the attached patch ?

use a default value that's fairly small. We were generating a result
of about 0.1, but I think 0.01 is probably better --- want to encourage
use of an indexscan in this situation.
costs using the inner path's parent->rows count as the number of tuples
processed per inner scan iteration. This is wrong when we are using an
inner indexscan with indexquals based on join clauses, because the rows
count in a Relation node reflects the selectivity of the restriction
clauses for that rel only. Upshot was that if join clause was very
selective, we'd drastically overestimate the true cost of the join.
Fix is to calculate correct output-rows estimate for an inner indexscan
when the IndexPath node is created and save it in the path node.
Change of path node doesn't require initdb, since path nodes don't
appear in saved rules.
to simplify constant expressions and expand SubLink nodes into SubPlans
is done in a separate routine subquery_planner() that calls union_planner().
We formerly did most of this work in query_planner(), but that's the
wrong place because it may never see the real targetlist. Splitting
union_planner into two routines also allows us to avoid redundant work
when union_planner is invoked recursively for UNION and inheritance
cases. Upshot is that it is now possible to do something like
select float8(count(*)) / (select count(*) from int4_tbl) from int4_tbl
group by f1;
which has never worked before.
command, the entries in template/.similar can really be regular
expressions. This isn't a new feature, just an observation of what the
code already did.
Makefiles now), there's no reason for os2client to maintain its own
copy of c.h just to change #define PORTNAME. Simplify Makefile
accordingly. Get rid of horribly-out-of-date modified copy of c.h,
which should never have been in the distribution to start with,
since it's actually a derived file. Now it's not needed anyway.
had already been transformed. This led to failure in examples like
UPDATE table SET fld = (SELECT ...). Repair this, and revise the
comments to explain that transformExpr has to be robust against this
condition. Someday we might want to fix the callers so that
transformExpr is never invoked on its own output, but that someday
is not today.
user, so it doesn't need to be translated from the number to the name.
also ``create database ...'' does not take numbers for the encoding, so
the ENCODING variable does not need to be translated to a number, but left
as the text representation. a patch is supplied to make the changes i
have found to work. i was successful dumping and reloading my database
after these changes.

incorrect descriptions of a couple of log-related functions.
I will not force an initdb for this, but log() on a numeric won't
work until you do one...
