Please enter a FULL description of your problem:
------------------------------------------------
I have tried to add a table to a database by importing the file by using
"-f" option for psql (psql -U -f file db).
If I use a file, a bit smaller than 900 byte - like 30_parser_error.sql
- it worked. Every other file, bigger than this one - like
"31_parser_error.sql", I used, did not work. There was always a error
message of the parser, saying that at the end of the file is an error -
see error message of 31_parser_error.sql in detail a bit further down.

Files and Error Messages of PSQL:

# psql -U postgres -f 30_parser_error.sql ghl
psql:30_parser_error.sql:30: NOTICE: CREATE TABLE will create implicit
sequence 'ghl_einricht30_id_seq' for SERIAL column 'ghl_einricht30.id'

31_parser_error.sql

# psql -U postgres -f 31_parser_error.sql ghl
psql:31_parser_error.sql:32: ERROR: parser: parse error at or near "("
#

First, I thought, it would be a SQL syntax error, like some spaces,
tabs, commas, ... but I could not find one. When I search in the FAQs, I
could find a message, somebody described a pretty similar behaviour of
psql, but with a much smaller sql statement (but not using the import
function).

Bug, somebody else reported in January 2002:
psql bug: copy paste statements looses tab character
http://archives.postgresql.org/pgsql-sql/2002-01/msg00220.php

The only difference, I could observe, was the size of the file. It might
be a problem of the size of a buffer - I have imported larger files via
psql -f with large INSERT statements and it worked. Now, I am not sure
if it is a problem of the file size.

Now, I send you both files, I used, so that you can reproduce the error.

Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------

Within a PostgreSQL database environment, just try to import the 2 files
from the command line.

My examples:

# psql -U postgres -f 30_parser_error.sql ghl

# psql -U postgres -f 31_parser_error.sql ghl

Find attached both files.

If you know how this problem might be fixed, list the solution below:
----------------------------------------------------------------------

Maybe I did not recognize a SQL problem or I missed to change the size
of a special buffer, I have not read about.

Thank you for solving the problem,
