Hello,
This is an actual problem that our customer hit. In ECPG, opening a cursor fails which is declared as follows:
EXEC SQL DECLARE cur CURSOR FOR
SELECT oid, datname
FROM pg_database
WHERE datname LIKE 'post%' ESCAPE '\' AND datconnlimit = :connlimit;
sqlstate: 07001
sqlerrm.sqlerrmc: too many arguments on line 30
The cause is that next_insert() in ecpglib unconditionally skips the next character after the backslash.
Could you review and commit the attached patch? I also attached the test program for convenience.
Regards
Takayuki Tsunakawa
