Bruce Momjian	181ca96e7a	August 6, 2002 ... 1. Reworked patch from Andrey Oktyabrski (ano@spider.ru) with functions: icount, sort, sort_asc, uniq, idx, subarray operations: #, +, -, |, & FUNCTIONS: int icount(int[]) - the number of elements in intarray int[] sort(int[], 'asc' | 'desc') - sort intarray int[] sort(int[]) - sort in ascending order int[] sort_asc(int[]),sort_desc(int[]) - shortcuts for sort int[] uniq(int[]) - returns unique elements int idx(int[], int item) - returns index of first intarray matching element to item, or '0' if matching failed. int[] subarray(int[],int START [, int LEN]) - returns part of intarray starting from element number START (from 1) and length LEN. OPERATIONS: int[] && int[] - overlap - returns TRUE if arrays has at least one common elements. int[] @ int[] - contains - returns TRUE if left array contains right array int[] ~ int[] - contained - returns TRUE if left array is contained in right array # int[] - return the number of elements in array int[] + int - push element to array ( add to end of array) int[] + int[] - merge of arrays (right array added to the end of left one) int[] - int - remove entries matched by right argument from array int[] - int[] - remove left array from right int[] | int - returns intarray - union of arguments int[] | int[] - returns intarray as a union of two arrays int[] & int[] - returns intersection of arrays Oleg Bartunov	23 years ago

Tom Lane	f933766ba7	Restructure pg_opclass, pg_amop, and pg_amproc per previous discussions in ... pgsql-hackers. pg_opclass now has a row for each opclass supported by each index AM, not a row for each opclass name. This allows pg_opclass to show directly whether an AM supports an opclass, and furthermore makes it possible to store additional information about an opclass that might be AM-dependent. pg_opclass and pg_amop now store "lossy" and "haskeytype" information that we previously expected the user to remember to provide in CREATE INDEX commands. Lossiness is no longer an index-level property, but is associated with the use of a particular operator in a particular index opclass. Along the way, IndexSupportInitialize now uses the syscaches to retrieve pg_amop and pg_amproc entries. I find this reduces backend launch time by about ten percent, at the cost of a couple more special cases in catcache.c's IndexScanOK. Initial work by Oleg Bartunov and Teodor Sigaev, further hacking by Tom Lane. initdb forced.	24 years ago
