If you neglect to do the typecasting and you assign + a float literal to a field of type float8, you may get incorrect values + stored! + * LIBPQ has been totally revamped so that frontend applications + can connect to multiple backends + * the usesysid field in pg_user has been changed from int2 to int4 to + allow wider range of Unix user ids. + * the netbsd/freebsd/bsd o/s ports have been consolidated into a + single BSD44_derived port. (thanks to Alistair Crooks) + +SQL standard-compliance (the following details changes that makes postgres95 +more compliant to the SQL-92 standard): + * the following SQL types are now built-in: smallint, int(eger), float, real, + char(N), varchar(N), date and time. + + The following are aliases to existing postgres types: + smallint -> int2 + integer, int -> int4 + float, real -> float4 + char(N) and varchar(N) are implemented as truncated text types. In + addition, char(N) does blank-padding. + * single-quote (') is used for quoting string literals; '' (in addition to + \') is supported as means of inserting a single quote in a string + * SQL standard aggregate names (MAX, MIN, AVG, SUM, COUNT) are used + (Also, aggregates can now be overloaded, i.e. you can define your + own MAX aggregate to take in a user-defined type.) + * CHANGE ACL removed. GRANT/REVOKE syntax added. + - Privileges can be given to a group using the "GROUP" keyword. + For example: + GRANT SELECT ON foobar TO GROUP my_group; + The keyword 'PUBLIC' is also supported to mean all users. + + Privileges can only be granted or revoked to one user or group + at a time. + + "WITH GRANT OPTION" is not supported. Only class owners can change + access control + - The default access control is to to grant users readonly access. + You must explicitly grant insert/update access to users. To change + this, modify the line in + src/backend/utils/acl.h + that defines ACL_WORLD_DEFAULT + +Bug fixes: + * the bug where aggregates of empty tables were not run has been fixed. Now, + aggregates run on empty tables will return the initial conditions of the + aggregates. Thus, COUNT of an empty table will now properly return 0. + MAX/MIN of an empty table will return a tuple of value NULL. + * allow the use of \; inside the monitor + * the LISTEN/NOTIFY asynchronous notification mechanism now work + * NOTIFY in rule action bodies now work + * hash indices work, and access methods in general should perform better. + creation of large btree indices should be much faster. (thanks to Paul + Aoki) + +Other changes and enhancements: + * addition of an EXPLAIN statement used for explaining the query execution + plan (eg. "EXPLAIN SELECT * FROM EMP" prints out the execution plan for + the query). + * WARN and NOTICE messages no longer have timestamps on them. To turn on + timestamps of error messages, uncomment the line in + src/backend/utils/elog.h: + /* define ELOG_TIMESTAMPS */ + * On an access control violation, the message + "Either no such class or insufficient privilege" + will be given. This is the same message that is returned when + a class is not found. This dissuades non-privileged users from + guessing the existence of privileged classes. + * some additional system catalog changes have been made that are not + visible to the user. + +libpgtcl changes: + * The -oid option has been added to the "pg_result" tcl command. + pg_result -oid returns oid of the last tuple inserted. If the + last command was not an INSERT, then pg_result -oid returns "". + * the large object interface is available as pg_lo* tcl commands: + pg_lo_open, pg_lo_close, pg_lo_creat, etc. + +Portability enhancements and New Ports: + * flex/lex problems have been cleared up. Now, you should be able to use + flex instead of lex on any platforms. We no longer make assumptions of + what lexer you use based on the platform you use. + * The Linux-ELF port is now supported. Various configuration have been + tested: The following configuration is known to work: + kernel 1.2.10, gcc 2.6.3, libc 4.7.2, flex 2.5.2, bison 1.24 + with everything in ELF format, + +New utilities: + * ipcclean added to the distribution + ipcclean usually does not need to be run, but if your backend crashes + and leaves shared memory segments hanging around, ipcclean will + clean them up for you. + +New documentation: + * the user manual has been revised and libpq documentation added. + +Postgres95 Beta 0.02 (Thu May 25 16:54:46 PDT 1995) +------------------------------------------------------ +Incompatible changes: + * The SQL statement for creating a database is 'CREATE DATABASE' instead + of 'CREATEDB'. Similarly, dropping a database is 'DROP DATABASE' instead + of 'DESTROYDB'. However, the names of the executables 'createdb' and + 'destroydb' remain the same. + +New tools: + * pgperl - a Perl (4.036) interface to Postgres95 + * pg_dump - a utility for dumping out a postgres database into a + script file containing query commands. The script files are in a ASCII + format and can be used to reconstruct the database, even on other + machines and other architectures. (Also good for converting + a Postgres 4.2 database to Postgres95 database.) + +The following ports have been incorporated into postgres95-beta-0.02: + * the NetBSD port by Alistair Crooks + * the AIX port by Mike Tung + * the Windows NT port by Jon Forrest (more stuff but not done yet) + * the Linux ELF port by Brian Gallew + +The following bugs have been fixed in postgres95-beta-0.02: + * new lines not escaped in COPY OUT and problem with COPY OUT when first + attribute is a '.' + * cannot type return to use the default user id in createuser + * SELECT DISTINCT on big tables crashes + * Linux installation problems + * monitor doesn't allow use of 'localhost' as PGHOST + * psql core dumps when doing \c or \l + * the "pgtclsh" target missing from src/bin/pgtclsh/Makefile + * libpgtcl has a hard-wired default port number + * SELECT DISTINCT INTO TABLE hangs + * CREATE TYPE doesn't accept 'variable' as the internallength + * wrong result using more than 1 aggregate in a SELECT + +Postgres95 Beta 0.01 (Mon May 1 19:03:10 PDT 1995) +------------------------------------------------------ +Initial release. |
