* Some points for portability improvements:Bruce Momjian2000-03-23
| | | | | | | | | | | | | | | | | | | 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 ? Andreas

* If we cannot get a real estimate for the selectivity of a range query,Tom Lane2000-03-23
| | | | | | 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.
* Improve selectivity estimation involving string constants: pay attentionTom Lane2000-03-23
| | | | | to more than one character, and try to do the right thing in non-ASCII locales.
* Repair logic flaw in cost estimator: cost_nestloop() was estimating CPUTom Lane2000-03-22
| | | | | | | | | | | | | 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.

* Restructure planning code so that preprocessing of targetlist and qualsTom Lane2000-03-21
| | | | | | | | | | | | | 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.

* transformExpr() did the Wrong Thing if applied to a SubLink node thatTom Lane2000-03-19
| | | | | | | | | 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.

* Another go-round with resolution of ambiguous functions and operators.Tom Lane2000-03-19
| | | | | | | | | | In function parsing, try for an actual function of the given name and input types before trying to interpret the function call as a type coercion request, rather than after. Before, a function that had the same name as a type and operated on a binary-compatible type wouldn't get invoked. Also, cross-pollinate between func_select_candidates and oper_select_candidates to ensure that they use as nearly the same resolution rules as possible. A few other minor code cleanups too.
* In can_coerce_type, verify that a possible type-coercion functionTom Lane2000-03-19
