PostgreSQL version: 7.4
Operating system: FreeBSD 4.8
Description: ecpg rejects C keywords in SQL context
Details:
ecpg 3.1.0
PostgreSQL 7.4.1
FreeBSD 4.8 on i386
gcc version 2.95.4 20020320 [FreeBSD]
ecpg seems to erroneously treat C keywords as errors in a SQL context. I
discovered this after upgrading to 7.4 and compiling an existing program
that refers to a column in one of my tables called "auto". The program
compiles successfully on 7.3.
Here's a simple one-line illustration of the problem:
$ echo 'exec sql select auto from foo;' >temp.pgc
$ ecpg temp.pgc
temp.pgc:1: ERROR: syntax error at or near "auto"
I would think that quoting the identifier would allow it to work:
exec sql select "auto" from foo;
but it doesn't seem to make any difference.
If I comment out the call to ScanCKeyword() at line 584 of
src/interfaces/ecpg/preproc/pgc.l, the example above will compile
succesfully.
