| Subject: | sqlt-diagram can't handle PostgreSQL schemas from pg_dump |
Hello, I found these db tools and tried to test, but without great
success with a PostgreSQL sql dump.
I attach a short example of a sqldump produced by pg_dump using pgAdminIII.
When executing this with the attached schema:
sqlt-diagram -d PostgreSQL mytestschema.sql
Error: translate: Error with producer
'SQL::Translator::Producer::Diagram': Can't call method "get_fields" on
an undefined value at
/usr/local/share/perl/5.8.8/SQL/Translator/Producer/Diagram.pm line 150.
When commenting even line 70 in the file out, it completely crashes:
sqlt-diagram -d PostgreSQL schema_pg_1table_1sequence.sql
gd-png: fatal libpng error: Image width or height is zero in IHDR
gd-png error: setjmp returns error condition
