Hello, We're investigating the migration of our LMS (Library Managment System) from Sybase ASE 15.7 to PostgreSQL 10.6. The used database in field have around 400 columns, some of them are also containing BLOB (bytea) data. The DB size vary upto 20 GByte. The interfaces contain any kind of language one could imagine :-) ESQL/C, JDBC, Perl DBD, ... Re/ the migration of the data itself, are there any use case studies which could we keep in mind? We plan to export the tables with our own tool which produces CSV with delimiter '|' (and \| if the char | is in char columns too) and with hex representation of the BLOB data. This seems to fit nicely with PostgreSQL's COPY command. Any known pitfalls?
Do you have many stored procedures, functions, etc? -- Angular momentum makes the world go 'round.
