Retire xlateSqlType/xlateSqlFunc; all type name translations are now handled as special productions. This is needed to keep us honest about user-schema type names that happen to coincide with system type names. Per pghackers discussion 24-Apr. To avoid bloating the keyword list too much, I removed the translations for datetime, timespan, and lztext, all of which were slated for destruction several versions back anyway.

#include "nodes/parsenodes.h"
Scanner performance improvements Use flex flags -CF. Pass the to-be-scanned string around as StringInfo type, to avoid querying the length repeatedly. Clean up some code and remove lex-compatibility cruft. Escape backslash sequences inline. Use flex-provided yy_scan_buffer() function to set up input, rather than using myinput().

Infrastructure for deducing Param types from context, in the same way that the types of untyped string-literal constants are deduced (ie, when coerce_type is applied to 'em, that's what the type must be). Remove the ancient hack of storing the input Param-types array as a global variable, and put the info into ParseState instead. This touches a lot of files because of adjustment of routine parameter lists, but it's really not a large patch. Note: PREPARE statement still insists on exact specification of parameter types, but that could easily be relaxed now, if we wanted to do so.

Clean up longstanding gcc warnings by adding missing extern declarations.

/* from scan.l */
Put back encoding-conversion step in processing of incoming queries; I had inadvertently omitted it while rearranging things to support length-counted incoming messages. Also, change the parser's API back to accepting a 'char *' query string instead of 'StringInfo', as the latter wasn't buying us anything except overhead. (I think when I put it in I had some notion of making the parser API 8-bit-clean, but seeing that flex depends on null-terminated input, that's not really ever gonna happen.)

PREPARE/EXECUTE statements. Patch by Neil Conway, some kibitzing from Tom Lane.

extern void parser_init(void);
Another PGINDENT run that changes variable indenting and case label indenting. Also static variable indenting.

extern int yyparse(void);
Functions live in namespaces. Qualified function names work, eg SELECT schema1.func2(...). Aggregate names can be qualified at the syntactic level, but the qualification is ignored for the moment.

pgindent run.

extern bool exprIsNullConstant(Node *arg);
Another pgindent run. Fixes enum indenting, and improves #endif spacing. Also adds space for one-line comments.

New pgindent run with fixes suggested by Tom. Patch manually reviewed, initdb/regression tests pass.
