* Ooops ... I had left some test coding in selfuncs.c thatTom Lane1999-08-211-6/+16

* Store -1 in attdisbursion to signal 'no duplicates in column'.Tom Lane1999-08-091-59/+4
| | | | Centralize att_disbursion readout logic.
* Further selectivity-estimation work. Speed up eqsel()Tom Lane1999-08-021-100/+168
| | | | | | | | | (it should just call the given operator, not look up an = operator). Fix intltsel() so that all numeric data types are converted to double before trying to estimate where the given comparison value is in the known range of column values. intltsel() still needs work, or replacement, for non-numeric data types ... but for nonintegral numeric types it should now be delivering reasonable estimates.
* First step in fixing selectivity-estimation code. eqsel andTom Lane1999-08-011-158/+445
| | | | | | | | | | neqsel now behave as per my suggestions in pghackers a few days ago. selectivity for < > <= >= should work OK for integral types as well, but still need work for nonintegral types. Since these routines have never actually executed before :-(, this may result in some significant changes in the optimizer's choices of execution plans. Let me know if you see any serious misbehavior. CAUTION: THESE CHANGES REQUIRE INITDB. pg_statistic table has changed.
